Explanation:
Answer:
480
Explanation:
resistance equals to potential difference divide by electric current
120÷0.25
=480
1500m = 1 sec
9000m/1500 = 6
So, it would take 6 sec to go 9000m
Answer:
9.38J
Explanation:
mass = 0.425kg
height (h) = 2.25m
g = 9.81m/s^2
Gravitational potential energy (PE) = mgh
Plug in all info you got:
(0.425kg)(9.81m/s^2)(2.25m) = 9.38J
