Explanation :

It is given that, Jamal wanted only to test the effect of the free fall and so he put his system in a vacuum to prevent air resistance.

Vacuum is also called as free space. In a vacuum there is no air resistance. We know that the air resistance depends on surface area.

But in the vacuum there is is no resistive force. So, in free fall both crumpled or flat paper will reach the ground at the same time.

A radio wave transmits 38.5 W/m2 of power per unit area. A flat surface of area A is perpendicular to the direction of propagati
Margaret [11]

Answer:

P=2.57\times 10^{-7}\ N/m^2

Explanation:

Given that,

A radio wave transmits 38.5 W/m² of power per unit area.

A flat surface of area A is perpendicular to the direction of propagation of the wave.

We need to find the radiation pressure on it. It is given by the formula as follows :

P=\dfrac{2I}{c}

Where

c is speed of light

Putting all the values, we get :

P=\dfrac{2\times 38.5}{3\times 10^8}\\\\=2.57\times 10^{-7}\ N/m^2

So, the radiation pressure is 2.57\times 10^{-7}\ N/m^2.
