Answer:
Force on the object is 20 N
Explanation:
As we know that work done to raise the book from initial position to final position is known as potential energy stored in it
So here we know that

here we know that
U = 30 J
s = displacement = 1.5 m
so we have


The Pancreas
<em>Is an inflammation organ that lies in the lower part of the stomach which plays a big part in the digestive system.</em>
Due to friction from sliding against the ground, the player decelerates in 1 direction. Thus his momentum decreases.
False, his first law states: An object that's in motion will remain in motion at a constant velocity unless it's acted on by an unbalanced force.
As per the question a frog jumps 5 m towards east.
Frog again jumps 2 m north.
Let the displacement along east is denoted by vector A and the displacement towards north is denoted as vector B.
Hence magnitude of A = 5 m
Magnitude of B = 2 m
We are asked to calculate the total displacement.
Here the angle between them is 90 degree as A is towards east and B is towards north.
As per parallelogram law of vector addition,the magnitude of total displacement [R] will be-


[cos90= 0]
