Answer:
B. 312.5 J
Explanation:
Work = change in energy
W = ½ mv₂² − ½ mv₁²
W = ½ m (v₂² − v₁²)
W = ½ (5 kg) ((15 m/s)² − (10 m/s)²)
W = 312.5 J

Answer:
The inductance of the coil is 20 mH
Explanation:
The coil is represented by inductance and resistance connected in series. The impedance of such a circuit is as follows:
We can use this relationship to determine the inductance:
