The potential energy of the body is "200 Joule".
According to the question,
Mass,
Height,
or,
= 2 m
As we know,
→ The potential energy will be:
=
By putting the given values, we get
=
=
Thus the above answer is right.

Answer:
The net outward force is exerted on a square window of the house is .
Explanation:
Given that,
Pressure = 1.02 atm
External air pressure = 0.910 atm
Distance = 2.03 m
We need to calculate the net outward force
Using formula of force
Where, P = pressure
F = force
A = area
Put the value into the formula
Hence, The net outward force is exerted on a square window of the house is .
Answer:1.549 kg-m/s
Explanation:
Given
mass of basketball =609 g
ball is moving downward right at an angle of with vertical
After hitting the floor it moves with a speed of 3 m/s
change in Momentum in x direction
where u=3m/s
v=3m/s
m=mass of ball
Change in momentum in Y-direction
