The forces of gravity between two objects are inversely proportional to
the square of the distance between them.  So reducing the distance
by 1/2 means increasing the gravitational force by 2² = 4 times. 
The 1 million newtons becomes 4 million newtons.

Note that this does NOT mean the satellite's altitude above the surface.
When you're calculating gravitational forces, it's the distance between
the centers of the objects.  So the question is a meaningful exercise
only if we use the distance between the satellite and the planet's center.

Use the kinetic-molecular theory to explain the compression and expansion of gases.
erma4kov [3.2K]

Answer:

According to the <u>kinetic-molecular theory of gases</u>, gases are composed of atoms and molecules (particles), where the distance among these elements is very large compared to their own size, therefore the total volume occupied by these particles is only a small part of the total volume occupied by the whole gas.

In other words: a gas has enough empty spaces in its total volume, therefore low density, which gives it the property of being highly compressible.

In this same sense, the kinetic-molecular theory of gases starts from the <u>first principle of thermodynamics</u>, establishing a relationship between <u>heat</u> and movement, since all material is composed of particles that are in motion (to a certain extent , depending on the state of matter), and in the case of gases the movement is greater, which is a strong indication of heat (thermal energy).

Now, gases can change their volume in two ways:

-By a change in temperature (heat transfer).

-By a change of pressure

So, this change or variation in volume is related to the work the gas does to change from an initial volume to a final volume.

Then, if in this process the volume decreases, it is said that the gas has been compressed (<u>compression</u> work); but if, on the contrary, the volume increases, the gas will have expanded <u>(expansion work). </u>

In this way, with the increase of the temperature of the gas, it is expanded by the increase of the kinetic energy of its molecules, but if an external pressure is applied it is compressed.

Communicating results allows scientists to learn from each other's results.
sveta [45]

True, scientists often talk to each other to figure out if their results were similar and what they could have done better.

Although, talking to other scientists does have risks, other scientists could copy your work and further better it.

So, your final answer is TRUE, sorry for the long answer, I needed to have a word count about 20 characters and then I got carried away! lol

Which of the following planets rotates in the opposite direction than the other planets? Venus Neptune Saturn Uranus
pogonyaev
Hello,

The answer is option A "Venus".

Reason:

The planet Venus spins the wrong way many scientists are not sure why. Its not options B, C, or D because these planets spin the same way the as each other. (besides Venus) Therefore the answer is option A.

If you need anymore help feel free to ask me!

Hope this helps!

An object 16.8 cm tall is placed in front of a converging lens. A real image, 46 cm tall, is formed on the other side of the len
worty [1.4K]

Answer:

2.74

Explanation:

Magnification = image distance/object distance

Mag = v/u

Given

v = 46cm

u = 16.8

Magnification = 46/16.8

Magnification = 2.74

Hence the magnification is 2.74
