How many moons does Jupiter (Saturn or Uranus) have?

Every night when you look up at the night sky, you may notice a moon gazing in between the million stars. It is not necessary that there will be a moon every night. Some nights the sky only consists of stars. That is known as new moon. When there is a thin sliver line it is known as a Crescent Moon. A half-full moon is known as a Half Moon. A moon that resembles to a full moon is known as a Gibbous Moon. A full moon is a Full Moon. The Earth has only one moon but there is news that there may be more. Even a man once lived on the moon and there is day and night. Here we will know about the moons of Jupiter, Uranus and Saturn.

How long does it take to get to the moon?

How long does it take to get to the moon? Till now, the shortest mission to go over the moon was NASA’s New Horizons Pluto mission. It had a fast launch with the Atlas V rocket speeding up to a velocity above 16 kilometers each second. At this degree, the rocket took only eight and a half hours to reach the moon starting from the earth. It is an excellent start for a probe that was going so far away to the ninth planet Pluto. Even though it is remarkable, one should know that the New Horizons was not decelerating when it was about to reach the orbit. Therefore, it was still going at a fast rate even after crossing the moon.

That is the shortest time taken to reach the moon. The lengthiest journey to the Moon was also a moderately current one and it was slow because it did not have modern parts. The good part is that is requires less energy and fuel. The name of the probe was European Space Agency (ESA) SMART-1 which took a year and a month to arrive on the moon. There are many diverse trails that a probe can use to get to the moon from the earth. The interspace from Earth to the Moon is around 360,000 km when it is the closest and 405,000 km when it is far away.

How long does it take to get to the moon

To get to the moon, the length is not important. It all depends on these factors

• The kind of rocket, probe or spaceship

• The level of fuel and energy efficiency

• The speed or the velocity of the space vehicle

As you can understand from the above examples of the fastest and the slowest missions to the moon, you can tell that it differs from spaceships to spaceships. There were many rockets from many different places all over the world to land on the moon and all had different times. The first one to reach the moon had the name, Luna 2. It came from the Soviet Union. It went there during 1959 and that was so long ago. Yet that managed to be on the moon within only 34 hours. It did not even take two days because it went straight to the moon.

The first person to reach the moon was Neil Armstrong. If NASA asks someone to land on the moon, they would think that they are trying to kill him. Neil Armstrong did not think that way neither did he have any insurance.  He was not alone, he was accompanied by Buzz Aldrin and Michael Collins. They had made their brilliant plan to help their family even after their death. They put their autographs on many papers and gave to a close friend. They were supposed to distribute it to their families. Therefore, when they pass away, each of their families would sell the autographs of the first people to land on the moon and make money.

How hot is the sun

How hot is the sun?

How hot is the sun? The surface of the sun’s temperature is 10112 Fahrenheit or 5600 degrees Celsius. The temperature inward into its core is 27,000,000 Fahrenheit or 15,000,000 Celsius. The temperature of the corona can be from 6000 degrees to a several million degrees. The temperature of the photosphere is around 10,000 degrees F or 5,500 degrees Celsius.

Have you ever wondered what is the Sun? It makes some days so hot that you feel like having cold drinks and ice-cream and nothing else. Some days, it just hides behind the clouds and makes the weather windy and cool. Do you think the temperature of the Sun decreases that day? No, it always has a steady temperature of 5600 degrees Celsius. The sun upholds its continual temperature over nuclear fusion and penetrating radiation. Atoms in the sun are continuously becoming more unbalanced and putrefying. While they decay, they give off particles and they that generate heat. Think of this occurring quadrillions of times each second so that you can receive heat. Presence of helium which were once hydrogen because of fusion causes strong blasts.

While there are contradictions and research saying that the temperature of the Sun does vary about five percent. The sun gets its strength from the nuclear fusion that creates one helium atom from four hydrogen ones. It is occurring more than several millions of time per second and as a result the hydrogen fuel is being finished. A central ball of metallic helium is rising in the core of the sun. The synthesis procedure takes place at the corner of the where the heat, pressure and temperature are highest. The extent of the central part of the sun will vary slightly in our generations, although it is uninterruptedly increasing. It is hard to understand therefore people consider it to be constant or steady although it is altering.

Just because it is hot or a ball of fire, do not make the mistake of thinking that its color is yellow and orange. It is a popular misapprehension that it is red, yellow or orange. Though, it is essentially all colors assorted together and come as the color white to our eyes. You can see them in photos clicked in outer space. Rainbows originate from it because they are light that has divided into its colors. Red has the longest wavelength and blue has the shortest and there are other colors like orange, yellow, green and violet. It is tough for many individuals, even experts, to confess that it is white in color. There were many times that the photo that shows it is white was made into orange. Besides, when the children at school are asked to draw a sun, some go with yellow, orange or even red. We can conclude saying that the temperature of the sun is or 5600 degrees Celsius at the surface. In the core it is 15,000,000 Celsius. The core is way hotter than the surface just like the Earth. Corona is a field made of Sun’s gas. The photosphere is the outer layer.

How to read literature like a professor

How to read literature like a professor

How to read literature like a professor? Listening to literature is interesting for the students as they can know about new things and stories. In fact, it is better than other subjects because it is simple to understand if the professor is reading along in the proper way. There are several things you need to notice and once you are careful, you will be reading like a pro in no time. There is a lot of difference between reading literature and other things.  If you are wondering how to read like one, then here are the steps.

How to read literature like a professor

How to read literature like a professor

It is a mistake than many new readers make because they forget the fact that they are trying to read like a professor. If you want to be elegant, you must read slowly. Not rushing through the lines will help the listeners understand what the story is about. The professor read slowly so that everyone in the class can comprehend the story and grasp what it is about. Slowly reading can be advantageous to you as well because you will not be making mistakes and remember you have to be very clear on your pronunciation. If you are reading at a fast speed, you might make mistakes like reading “on” as “no” and etc.

Step 2: Know the book

Since you are trying to read like a professor, first of introduce yourself to the book. Ask yourself why you want to choose the book to read for others. Knowing the idea and the answer of why you are reading this can make the reading more beautiful. Before you read something to others make sure you know the overview and why should others hear it. Does it come with eligible information for the audience? Is there anything bad about it or is there any reason to avoid the book? You have to read it yourself first and look for more information about it. That means, browse on the internet for reviews and overviews about it. Find out if there is anything wrong about it. Try to grasp the concept of the book for proper reading. If you read it several times or at least once by yourself, it will become easy to read it like a pro.

Step 3: Bookmark special areas

While you are reading it, there can be many sorts of important things since it is literature, there will be places where the listeners will get excited, sad or happy. Give them the chance to express their feelings as you read along and you should bookmark the areas that are important so that you can stop and give them the chance to express their feelings. You should do it too instead of blankly just reading it aloud. You can even match your voice tone to the special lines. For example, “she cried the whole night thinking there is no hope” make your tone sad not happy or amazed. Reading is one of the best thing ever that some can do but the way you are reading is important.


• Do not make the mistake of reading at the same tone or same speed throughout the story.

Do you think that the everyday 24 hours is exact the same? You think that your watch is telling you everything but it is not.  There are forces altering the velocity of the rotation of the Earth. The effect is so small that it is hard to notice. The gravitation forces cause tides by the gravitational forces amid the Earth and from the outer space, the moon, sun etc. causes drag force as they interrelate with this planet. That tidal friction is an additional 2.3 milliseconds to each day.  Meteorological conditions structures can alter the Earth’s spin, with airstreams smearing a decelerating force to Earth’s surface. Lastly, earthquakes can muddle with the span of a single day by essentially reallocating the planet’s mass. For example, earthquake that hit Japan during 2011 in fact fast-tracked the Earth’s rotation (since it lifted the mass on the way to the center of the Earth) and reduced the 24 hours by 1.8 microseconds.

How fast does the earth spin

This planet is spinning on its axis one time for each 24 hours. In the center of the Earth, the rate of Earth’s spin is aroun1,000 miles per hour (1,600 km/h). Each day consists of 24 hours and we all experience day and night on regular routine but we never notice the spin or the rotation. We do not understand the spin since everything on the planet like humans, atmosphere and Earth’s oceans are circling laterally with the Earth at the identical continual rate.

The land feels secure and hard underneath your feet. Even though the planet is continuously spinning, we are still stable. The secret to our stability and firmness is the gravity.  The other reason is momentum. So, you can say for this two things: gravity and momentum you do not feel the earth spin. The external part of the Earth is stirring at 1675 km/h or 465 meters/second. It is 1,040 miles/hour.

Here is the calculation: 

The circumference at the equator is equal to 40,075 km and the total time to complete one rotation on its axis is 23.93 hours. 40,075 km ÷ 23.93 hours = 1,675 km/hour or 465 meters per second.

Divide the distance by the time. We did not take it as 24 hours because astronomers calculate a day in two ways and it results in the day being 23 hours and 56 minutes. They name it as a sidereal day. The Sun also requires an additional four minutes every day.

Now that you saw the calculation and you know the reasons why the Earth spin changes and how we remain stable. When you are on a plane or car, you think you are stable or you may feel like you are not moving at all.  As we mentioned about the watch, you may want to put some additional seconds to it as the Earth’s rotation is decelerating down by two-thousandths of a second each day.

How to find the area of a trapezoid

There are six variations of quadrilaterals—rectangle, parallelogram, rhombus, kite, trapezoids, and squares—and with the exception of a rhombuses and kites, each has a different method for calculating the area. The area of a quadrilateral is the number of square units on its surface, which is a figurative way of saying “the space between the lines”.  To simplify, think of an area rug. The amount of space it takes up on your floor is its area. Abstract shapes are no different, and square units have virtually unlimited practical use in complex mathematics. A trapezoid is a type of polygon called a convex quadrilateral, which means it is a shape of four sides with at least two of these sides running parallel to each other.  It is similar to a parallelogram, which has two pair of parallel sides, and a rectangle, which also has two parallel sides but all right angles. However, the area formula has slight variations, which we will discuss below.

The formula for finding the area of a trapezoid is base plus base times height, divided by two, or:

How to find the area of a trapezoid

Observe the image of the trapezoid on the right to identify the which lines are which.  Despite base implying the bottom line, it actually refers to both the horizontal line at the top and the one at the bottom.  The height requires measuring the length from base to base, which unlike a square, is not always the same as the length of the sides because they can be at angles that make them longer.  Notice that the measurement for height, marked h, was taken using the right angle between the bases (a and b), instead of the line between angles D and A. To find the area of the pictured trapezoid and any other, you would follow these steps:


1) Find the length of lines a and b and add them together.

2) Take the result of that, and multiply it by the length of line h.

3) Divide the result of the first two steps by 2.


When calculating the area of a trapezoid, it is important to follow order of operations in this formula as it is with all mathematical procedures. If you’re not familiar with order of operations, memorize the PEMDAS method to help you remember which to do first.  This one’s pretty straightforward because it has parenthesis to show which one comes first (the P in PEMDAS), but many mistakes are made for doing one step before the other in a math problem. You may also encounter problems where some of the numbers are missing and you need to find additional methods to calculate their values before you can complete the equation, though in most situations it is acceptable to substitute the variable x for unknown quantities and leave it as such in the answer.  For example, in this problem we don’t know the length of the first base: =  =

When we figure out that the value for x is 6, it we can plug it in:  =
