C.
Explanation:
As a pendulum swings from its highest to its lowest position along an arc, what happens to its kinetic energy and potential energy? The potential energy decreases while the kinetic energy increases.
Newton’s first law state that an object in motion stays in motion unless acted upon force so the answer would be RESISTANCE

I got the answer wrong and my teacher told me that c is the right answer choice
Answer: The mass of air present in the room is 37.068 kg
Explanation : Given,
Length of the room = 10.0 ft
Breadth of the room = 11.0 ft
Height of the room = 10.0 ft
To calculate the volume of the room by using the formula of volume of cuboid, we use the equation:
where,
V = volume of the room
l = length of the room
b = breadth of the room
h = height of of the room
Putting values in above equation, we get:
Conversion used :
Now we have to calculate the mass of air in the room.
Conversion used : (1 kg = 1000 g)
Therefore, the mass of air present in the room is 37.068 kg
