A battery supplies 22V to a circuit with a 20. Ω resistor. What is the current of the circuit?

I=22 ÷20

Explanation:

then put the on the calculator you'll get you answer

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.

a and b sometimes have a positive value
