200 N, that is if the force is balanced and the wall doesn't move
Frequency is not a length of time. It's exactly the opposite.
Frequency tells you how often something happens. In fact,
the unit 'Hz' means 'per second'.
Frequency of 2 Hz means "It happens at 2 per second."
The time it takes for the thing to happen once is exactly the
'reciprocal' of the frequency ... ' 1 ' divided by the frequency.
If the frequency is 2 Hz, then the thing happens every 1/2 second.
If the frequency is 74 Hz, then it happens every 1/74 of a second.
If the frequency is 1 KiloHz, then it happens every 1/1000 second.
