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:
B
Explanation:
You can heat it and then let it cool in a very strong magnetic field.
“RESISTANCE” is a property that determines how much current will flow for a given source voltage, whereas a “RESISTOR” is a device that controls the current in a circuit.

2 should be placed in the blank to make the equation balance. Btw, that's chemistry and not physics. Get it right.
