An empty paper cup is the same temperature as the air in the room. A student fills the cup with cold water. Which of the following describes how thermal energy is transferred?
O Thermal energy is transferred from the cold water to the cup until they are at the same temperature.
O Thermal energy is transferred from the cup to the cold water until they are at the same temperature.
Thermal energy is transferred from the cup to the cold water until the cup has no more thermal energy
Thermal energy is not transferred between the cup and the cold water.

Thermal energy is transferred from the cup to the cold water until they are at the same temperature.

Explanation:

In the normal pattern thermal energy is usually transferred from a warmer surface to a cooler surface.

In this case, the warmer surface is the cup and the colder surface is the cold water. Thermal energy is transferred from the cup to the cold water until they are at the same temperature.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
