If an ac waveform has a maximum voltage of 24 vac, what's its peak-to-peak voltage measure?

48 V

Explanation:

Alternating voltage is the sinusoidal voltage which varies according to the time .

It travels in the form of sine curve as shown in the diagram .

The peak value of voltage is the maximum value.

We get two peaks, one positive and the other is negative.

So the distance between the peak to peak value is 24 + 24 = 48 V

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.
