Answer:
The value of radiation pressure is 
Pa
Explanation:
Given:
Intensity 
Area of piece 
From the formula of radiation pressure in terms of intensity,
Where 
radiation pressure, 
speed of light
We know value of speed of light,
Put all values in above equation,
Pa
Therefore, the value of radiation pressure is Pa
Ohh this is quite a lot umm i’ll be back hold on
If a surface looks "shiny" to you, that's because it reflects all
or most of the visible light that hits it. That doesn't always mean

Answer:
The forces could be gravity, friction between the car and the ground, the force Katie is applying and the normal reaction.
It defines that if two thermodynamic systems are each in equilibrium with a third system, then they are in equilibrium with each other.
