The mass of the (elevator + person) is (2,000 kg + 60 kg) = 2,060 kg .
The weight is (mass x gravity) = (2,060 x 10) = 20,600 newtons
Work = (force x distance) = (20,600 newtons x 24m) = <em>494,400 joules</em>
The speed, acceleration, and how much time it takes don't make any
difference, unless you want the average power during the lift.
Power = (work)/(time) =
494,000 J / (24/4 m) =
494,000 J / 6 sec = <em><u>82,400 watts</u></em> wow !
Answer:
c. V = k Q1 * Q2 / R1 potential energy of Q1 and Q2 separated by R
V2 / V1 = (R1 / R2) = 1/4
V2 = V1 / 4
Answer:
12500(kg*m/s)
Explanation:
F=ma=mv/t=p/t
p=F*t=500N*25 s=12500(kg*m/s)
Here is the answer. What is happening at the atomic level to give rise to the observed energy is that t<span>he </span>atomic level<span> is affected by the movement of electrons so as to </span><span>give rise to the observed energy. Hope this answers your question. Have a great day!</span>
