As nitrogen makes up 78% of the atmosphere, there is no shortage of it – it just isn't in a form plants and animals can use.

How does transferring energy into a container of magnetic marbles affect the speed by shaking the container gently?

Answers

By the transfer of energy into a container of magnetic marbles the speed changes because of kinetic energy produced by the shaking of container gently. This will lead to phase changes.

What is kinetic energy?

All the phase changes in a system are accompanied by the change in the energy of a system. These include transfer of kinetic energy to a system. Changes from a more-ordered state to a less-ordered state are endothermic reactions. Changes from a less-ordered state to a more-ordered state are always exothermic reactions.

A phase change in a system takes place when a matter changes from one state to another state. These changes occur when sufficient amount of energy is supplied to the system or lost from the system. Phase changes also occur when the pressure on the system is changed.

Felipe believes that whenever the Moon is in the position that is shown from above (top view) in Diagram A, the Moon always looks completely bright in the view from Earth, as shown in Diagram B. Is Felipe correct? If he is correct, explain why the Moon always looks bright from Earth in that position, and explain how he should show light on the Moon in Diagram A. If he is incorrect, explain how else the Moon can look when it is in that position.

Answers

Answer: Felipe is wrong.

Explanation:

In diagram A, we can see that the light comes from the left, it first impacts on the Earth, and then we have the Moon.

Now, you can model this situation with a flashlight (the Sun) a basketball (the Earth) and a tennis ball (the Moon)

When you point with the flashlight at the basketball, the basketball will look bright, but it will cast a shadow behind it. This shadow will cover the tennis ball, and almost no light will reach the tennis ball, so it will not look bright.

This phenomenon is called a lunar eclipse, and this happens when the Earth is in between the Sun and the Moon. When this happens, we see the moon a bit darker and more reddish.

Felipe is incorrect, as it will not be possible to see the moon if it is in the position shown in the diagram.

We can come to this answer because:

It is only possible to see the moon when it is reflecting sunlight.In this case, no other type of celestial body must be in front of the moon, blocking the sunlight.As we can see in the question above, sunlight is being emitted from left to right.Although the moon is in the right direction to reflect this light, the earth is in front of the moon.Therefore, sunlight will not shine on the moon, because the earth will block it and cast a shadow over the moon.

Therefore, it will not be possible to see the moon, as Felipe said.
