Answer:
Current = 8696 A
Fraction of power lost =
= 0.151
Explanation:
Electric power is given by

where I is the current and V is the voltage.

Using values from the question,

The power loss is given by

where R is the resistance of the wire. From the question, the wire has a resistance of
per km. Since resistance is proportional to length, the resistance of the wire is

Hence,

The fraction lost = 
1. Kinetic
He makes the ball move by kicking it, which increases the kinetic energy
Answer:
the answer is B
Explanation:
speed is the rate at which the distance covered changes or the distance divided by the time taken.
scalar is always positive.
Answer:
35, I got you bro, i got you
Work = (force) x (distance) =
(200 N) x (3.5 m) = <em>700 joules</em>
