I think it might be a gravitational pull
Answer:
Explanation:
Given that
Mass of bowling ball M1=7.2kg
The radius of bowling ball r1=0.11m
Mass of billiard ball M2=0.38kg
The radius of the Billiard ball r2=0.028m
Gravitational constant
G=6.67×10^-11Nm²/kg²
The magnitude of their distance apart is given as
r=r1+r2
r=0.028+0.11
r=0.138m
Then, gravitational force is given as
F=GM1M2/r²
F=6.67×10^-11×7.2×0.38/0.138²
F=9.58×10^-9N
The force of attraction between the two balls is
F=9.58×10^-9N
<span>The initial momentum is 5 kg m/s and the final momentum is 10 kg m/s
'cause P = m*v, when we increase either m or v, P also increases by the same expression,
P = 5 * 2 = 10
So, option D is your answer!!
Hope this helps!

Answer:
Because the uncontrolled and unreasonable use of energy resources in the past few decades has led to the depletion of conventional type of resources. Although, measures are taken at the government levels to control the energy consumption, these attempts only meet with little success. Public awareness is the only way to successfully deal with this problem.
Explanation:
The pressure exerted by fluid at any given depth is exerted equally in all directions.
<h3><u>Explanation:</u></h3>
Pressure is defined as the force per unit area. Hydraulic force is the force that is exerted by liquid to a particle which is present somewhere inside the liquid. This pressure is exerted by the liquid particles from each part of the of the whole mass.
As far as the upper particles are concerned, the liquid exerts the force due to gravity, which acts downwards. Similarly, the particles which are down to the particle in liquid gives the reaction force which is based on Newton's third law of motion. This makes the force acts from all sides.
This is the reason why a particle which is submerged stays still, as there's no unbalanced force which can turn the particle.
