Answer:
Step-by-step explanation:
The work done changes the potential energy
ΔPE = mgΔh = 450(10)(50) = 225,000 = 225 kJ
power is the rate of doing work
P = 225000/5 = 45000 W = 45 kW
1 foot is 12 inches
336/12=28
yes it is bigger
<span>12.6 • (–4) ÷ 12 • (–3) ÷ 0.5
= -50.4 </span>÷ 12 • (–3) ÷ 0.5
= -4.2• (–3) ÷ 0.5
= 12.6 ÷ 0.5
= 25.2
