Answer:
Power, P = 30 W
Explanation:
We have,
Voltage drop of a circuit is 60 V
Resistance of the resistor is 120 ohms
Current across the circuit is 0.5 A
It is required to find the power conducted by the resistor. Power conducted by a resistor is given by :
V and I are voltage and current
So, the power conducted by the resistor is 30 watts.

Answer:
The magnitude of the acceleration of the box is 2 m/s².
Explanation:
Given:
Mass of the box, kg
Force acting towards east, N
Frictional force acting towards west, N
Let the acceleration be m/s².
Now, net force acting on the box towards east is given as:
From Newton's second law of motion,
Therefore, the magnitude of the acceleration of the box is 2 m/s².
