The equation of the graph is
Force = (mass) x (acceleration) .
The graph is a straight line that passes through the origin,
and its slope is the mass of the object being studied.
Answer:

Explanation:
Power is related to energy by the following relationship:

where
P is the power used
E is the energy used
t is the time elapsed
In this problem, we know that
- the power of the fan is P = 120 W
- the fan has been running for one hour, which corresponds to a time of

So we can re-arrange the previous equation to find E, the energy (in the form of thermal energy) released by the fan:

Frequency = 1/time period = 1/0.05 = 20s^-1.
