Answer:
Data:-m=0.88kg ,g=9.8m/sec² ,P.E=96J ,h=?
Explanation:
solution ,P.E=mgh here we have to find h so h=P.E/mg ,h=96/0.88×9.8 ,h=96/8.624=11.131m and if you want to verify so just put the value of h in same formula, likewise :-P.E=mgh ,P.E=0.88×9.8×11.131=96J so we got the same value of P.E as it is given the question (verified).
Answer:
Power = Current × Voltage
Explanation:
Units:
Power = Watts
Current = Àmperes
Voltage = Volts
In soccer, the ball is potential energy. When you kick the ball, it becomes kinetic energy.
<span>PE = m * g * h
PE = 60 * 9.8 * 4
PE = 2352 J
Power = E/t
Power = PE/t
Power = 2352/4.2
Power = 560 Watt</span>
