Answer:
A = 10 m amplitude
m = 3 kg mass of object
Vm = 5 m/s
w A = Vm where w = omega
w = 2 * pi * f
2 * pi * f 10 = 5
f = 5 / (20 * pi) = .0796 / sec

Answer:
16.5 kwh and 59400 kJ.
Explanation:
kWh is a measure of energy that is equivalent to the power in kw times the number of hours the device worked.
In this case, it would be equal to:

1 kw also means 1kj of energy spent per second. With this, we calculate the amount of energy in kJ spent by the resistance:
