Answer:
a) P' = P_original, b) P ’= P_original + ρ g Δh
Explanation:
The expression for nanometric pressure is
P = ρ g h
where ρ is the density of the liquid and h is the height
a) we change the radius of the barrel, but keeping the same height
as the pressure does not depend on the radius it remains the same
P' = P_original
b) We change the barrel height
h ’≠ h
we substitute in the equation
P ’= ρ g h’
h ’= h + Δh
P ’= ρ g (h + Δh)
P ’= (ρ g h) + ρ g Δh
P ’= P_original + ΔP
In this case, the pressure changes due to the new height,
*if it is higher than the initial one, the pressure increases
*if the height is less than the initial one, the pressure is less
Answer: Socratic
Explanation: i’m not sure but you can use Socratic it’s a good app that helps

Answer:
A push or pull exerted on an object
Answer:
The speed of the stone is 0.6138 c.
(B) is correct option.
Explanation:
Given that,
Mass of stone m= 0.6
Relativistic mass = 0.76
We need to calculate the speed
Using formula of rest mass
Put the value into the formula
Hence, The speed of the stone is 0.6138 c.
