Answer:

C - 3,720 J, 1,950 J

Explanation:

Hello

Epotential = M*G*H

Ep = (4)(9.8)(145-50)

Ep = 3729 J

Then

Ec = 1950 J

Best regards

In a parallel circuit, the first resistor has a resistance of 4 Ω and a current of 4 A. The second resistor has a resistance of
9966 [12]
Voltage across 1st resistor = I x R = 16 volts
thus voltage across 3rd resistor is also 16 volts.

resistance = V/I = 16/6 =2.7 Ω
