Answer:

U = 5/2 NkT.

Explanation:

A diatomic molecule = H₂, O₂, N₂ .....etc

A diatomic molecule has 5 degrees of freedom.

3 transnational modes = x, y, z
2 rotational modes = ωx , ωy

So, the internal energy for diatomic gases is :

U = 5/2 NkT.

An output is a Push or pull _________________________ on the object

Ugo [173]

Answer:

The input force that you use on an inclined plane is the force with which you push or pull an object. The output force is the force that you would need to lift the object without the inclined plane. This force is equal to the weight of the object.

A uniform brick of length 21 m is placed over

Paha777 [63]

Answer:

15.75 m

Explanation:

First, let's look at the top brick by itself. In order for it not to tip over the bottom brick, its center of gravity must be right at the edge of the bottom brick. So the edge of the top brick must be 10.5 m from the edge of the bottom brick.

Now let's look at both bricks as a combined mass. We know the total length of this combined brick is 10.5 m + 21 m = 31.5 m. And we know that for it to not tip over the edge of the surface, its center of gravity must be at the edge. So the edge of the combined brick must be 31.5 m / 2 = 15.75 m from the edge of the surface.
