Answer:
10.5min
Explanation:
Given parameters:
Distance = 4200m
Speed = 400m/min
Unknown:
Time taken for this run = ?
Solution:
Speed is the distance divided by the time taken.
Speed =
Time =
Now insert the parameters and solve;
Time =
= 10.5min
You can describe kinetic energy and the potential energy of motion to get your answer.
Explanation:
V=IR; I=V/R
V=120V, R=10
I= 120/10=12
The current in the circuit is 12A
