Pressure is defined as the force acting perpendicular on an unit area of the surface.
OR
The thrust per unit area is called Pressure.
let us see, on what factors the pressure depends?
Take a pin having a pointed end and a nail having blunt end. Press then against a cardboard by applying the same force. We find that the pin penetrates deep into the cardboard then the nail. In this case, force acting on two points of the cardboard is same but the area under the tip of the Pin is less than under the tip of the nail.
The effect of the forces of the scene magnitudes on the different area is different.
Conclusions : Pressure acting on the surface is inversely proportional to the area of the surface on which force acts.

Answer:
P = 400248 [Pa]
Explanation:
We can calculate the hydrostatic pressure exerted by a column of liquid by means of the following equation.
where:
Ro = density = 1020 [kg/m³]
g = gravity acceleration = 9.81 [m/s²]
h = depth = 40 [m]
Therefore:
![P=1020*9.81*40\\P=400248 [Pa]](https://tex.z-dn.net/?f=P%3D1020%2A9.81%2A40%5C%5CP%3D400248%20%5BPa%5D)
Increases as well since more friction causes less speed and thus less potential energy and more kinetic energy.
Let us assume that the definition of frequency, wavelength and wave speed is determined by the function
Here,
v = Velocity of wave
= Wavelength
f = Frequency
We know that the earth has the ability to absorb visible light but that it can also emit a longer radiation wavelength. This assessment allows us to confirm that option A. Is correct. In turn, if said wavelength is large, being inversely proportional to the frequency,
This does tend to be lower radiation. The correct options are:
A.The earth absorbs visible light and emits radiation with a longer wavelength.
B.The earth absorbs visible light and emits radiation with a lower frequency.
