Answer:
t is not moving.
It must be moving left.
It must be moving right.
It is being moved in an unknown direction
Answer is: It must be moving right
Explanation:
M= 130 kg
v= 5 m/s
kinetik energy = ½• m•v²
= ½ • 130• 5²
= ½•130•25
= ½•3250
= 1625.
Answer:
98%
Explanation:
Given parameters
Mass of motor = 10kg
Height = 2m
Time = 2s
Power input = 100w
Unknown
Efficiency = ?
Solution
Efficiency is the percentage of the power output to the power input.
Power is the rate at which work is done.
Power output = mass x g x height / time
g is the acceleration due to gravity
Power output = 10x 2 x 9.8 / 2 = 98W
Efficiency = power output/ power input x 100
Efficiency = 98/100 x 100 = 98%
<h3>Answer: any path that allows electrons to flow</h3>
An electrical circuit is a path in which electrons from a voltage or current source flow. ... The part of an electrical circuit that is between the electrons' starting point and the point where they return to the source is called an electrical circuit's "load".
