Probably a. Reactivity.
Because molecules REACT to heat and coldness by going crazy when there is heat and by freezing up when its cold
The time it takes "to complete one cycle" is a perfect definition for <em>period</em>.
So the <em>2 sec</em> that you measured is the swing's period.
Frequency is just 1/period (the 'reciprocal' of the period).
For this swing, the frequency is 1/(2sec) = 0.5 per second = <em>0.5 Hz</em>.
( "Hertz" means "per second")
Answer: P = 5.44 KW
Explanation:
The formula for calculating power is expressed as
P = VI
where
v is the voltage
I is the current
From the information given,
v = 320
I = 17
Thus,
P = 320 x 17 = 5440 W
We would convert it to KW by dividing by 1000. It becomes
P = 5440/1000
P = 5.44 KW
