<h3>
Answer:</h3>
20 seconds
<h3>
Explanation:</h3>
<u>We are given</u>;
- Power of the engine as 400 watts
- Force as 100 N
- Distance the object is lifted up as 80 m
We are required to determine the time taken.
- We need to know that power is the rate of work done
Therefore;
But, work done = Force × distance
Work done = 100 N × 80 m
= 8000 Joules
- Since , Power = Work done ÷ time
Then, time = Work done ÷ Power
Thus;
Time = 8000 J ÷ 400 W
= 20 s
Therefore, the time taken by the engine to lift the object is 20 seconds
Answer:
Interact with it
Explanation:
The body in a condensed form (often a dot or a box)
Straight arrows pointing in the direction in which forces act on the body are represented.
Moments are portrayed by curved arrows pointing in the direction in which they impact the body.
A coordinate system is a series of coordinates.
I think the correct answer among the choices listed above is option B. The acceleration of gravity is a constant equal to 9.8 meters per second squared. You can see that all things fall at this rate if there is no air resistance in a system or when in a vacuum.
