The change in the gravitational potential energy is represented by the equation
u = ΔPE = Δmgh
since the mass of the system will remain constant and the acceleration due to gravity will also remain constant, the equation will become
u = mg Δh
Answer:1725 watts
Explanation: Household devices are required to run at 110-125 volts and most are rated at 115 volts so 1725 watts for a 15 amp cord or circuit. You will have to be careful when adding outlets for a 15 amp breaker. Always be sure to consult a licensed electrician before DIY electrical work.
Answer:
5m/s²
Explanation:
<em>acceleration= change in velocity divided by change in time</em>
<em>time= 3 seconds</em>
<em>Iv= 8 m/s north</em>
<em>Fv= 23 m/s north</em>
<em>change in velocity = 15 m/s</em>
<em>acceleration = 15 / 3 which equals 5 m/s²</em>
