Answer:
The mass of the second student is 20.180 Kg
Explanation:
When the mass is added on one piston, it causes a change in pressure on other piston.
The change in mass is calculated using the formula,
Δm=ρhA/g
The calculated radius of piston is 0.46 m.
Given h=35 cm= 0.35 m.
Assume ρ=850 kg/m^3
So Δm=850*0.35*π*(0.46)^2/9.8
Δm= 20.180 Kg

EQUATOR IS THE LINE THAT DIVIDES EARTH INTO TWO HEMISPHERES .
The effects of nuclear power plants are much less harmful to the environment than that of coal-fired stations due to greenhouse gasses emitted by coal-powered stations.
<h3>What are the differences between these types of power?</h3>
Nuclear power plants will last much longer than that of coal-fired stations given that the coal-powered plants rely on a finite natural resource. Nuclear power plants are also much safer and cleaner for the environment <u>if handled and cared for correctly</u>. This is due to the large amounts of greenhouse gasses emitted by coal burning.
Therefore, we can confirm that nuclear power plants are much less harmful to the environment than coal-fired stations due to greenhouse gasses emitted by coal-powered stations.

Gravitational Potential Energy (GPE) before fall = Kinetic energy on impact
GPE = mgh
GPE = 5kg x 9.8m/s^2 x 10m
GPE = 490 J
Kinetic Energy = 490 J
(This is assuming that gravitation field strength (g) is 9.8m/s^2, sometimes you may round this to 10m/s^2, therefore making the final result:
Kinetic energy = 500 J)
