Answer: Fnet = 40 N on the right
Explanation: The net force is the summation of forces acting on an object. Add the forces in the same direction and subtract to the opposing force moving in the opposite side.
Fnet= F1 + F2 - F3
= 120 N + 60 N - 140 N
= 180 N - 140 N
= 40 N on the right
Answer:
525,000J
Explanation:
Power = work/time
Given
Power = 350 watts
Time = 25 mins = 25 x 60 = 1500 secs
Therefore
350 = work/1500
Cross multiply
Work = 350 x 1500
Work = 525,000J

Answer: The rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.
Explanation:
- The rate of energy transfer from one point to another is known as power.
- Its SI. unit is <em>Watt.</em>
Formula to compute power:
Power = , I = cureent, R = resistance.
Given R = 5 ohm , Current = 0.5 A.
Then, power =
Hence, the rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.
