Explanation:
The pulley is modelled by the Newton's Laws, whose equation of equilibrium is:
Given that tension is equal to the weight of the bucket, the angular acceleration experimented by the pulley is:
Answer:
4 A
Explanation:
V = IR, where V=voltage, I=current, R=resistance. This is Ohm's Law. (remember that for units V = volts, Ω = ohms, A = amperes.)
V = IR
12 V = I * 3 Ω
12/3 = I
<u>I = 4 A</u>
