The two main states of mechanical energy are potential energy and kinetic energy. Potential energy, in terms of mechanical energy,
Explanation:
Initial dimension of the pool:
Length (L)= 50.0 m
Width (W)= 25.0 m
Depth (D) = 2.0 m
Initial Volume of the pool (V1) = L*W*D = 50.0 * 25.0 *2.0 = 2500 m3
When the depth is lowered by 3 cm i.e. 0.03 m, the new depth becomes: 2.0 - 0.03 = 1.97 m
The new volume of the pool (V2) = 50.0*25.0*1.97 = 2462.5 m3
Volume of water to be pumped out = V1-V2 = 2500-2462.5 = 35.5 m3
Now, 1 m3 = 1000 L
therefore, 35.5 m3 == 35.5 *10^3 L
It is given that:
3.80 L of water is pumped out in 1 sec
Therefore, 35.5*10^3 L will be pumped out in:
= 1 s * 35.5*10^3 L/3.80 L = 9.34*10^3 sec
QUICK ANSWER
Large bodies of water will impact the temperature by releasing energy slowly and absorbing heat from the Sun, which cools areas that are near large bodies of water and moderates the Earth's temperature. The process begins with with the Sun's energy and the radiation that comes off of the Earth's surface.
