The potential energy is 4.10 J
Explanation:
The potential energy of a body is given by
where
m is the mass of the object
g is the acceleration of gravity
h is the height of the object relative to the ground
For the lemming in this problem we have
m = 0.078 kg is its mass
h = 5.36 m is the height above the ground
is the acceleration of gravity
Solving the equation,

A sound wave is a longitudinal wave
To solve this problem it is necessary to apply the concepts related to rate of thermal conduction
The letter Q represents the amount of heat transferred in a time t, k is the thermal conductivity constant for the material, A is the cross sectional area of the material transferring heat, , T is the difference in temperature between one side of the material and the other, and d is the thickness of the material.
The change made between glass and air would be determined by:
There are two layers of Glass and one layer of Air so the total temperature would be given as,
Finally the rate of heat flow through this windows is given as,
Therefore the correct answer is D. 180W.
