Answer:
D. The state of motion of an object with mass
Explanation:
Specifically, momentum is mv, mass times velocity
The area of a second piston that exerts a force of 24,000 N is 0.04
.
Gravitational force is measured in newtons. Utilizing the physics formula pressure = force/area, you can compute pressure if you know the value of a force. Both pounds per square inch (psi) and newtons per square meter (N/m2) are acceptable units of measurement for this pressure.
Given force 1 = 12,000 N
The pressure which has produced a force of 12,000 N at the piston 1 = Force/ area
= 12,000N / 0.020 
= 6,00,000 N/
Now force at piston 1 must be equal to force at piston 2. thus, force at piston 2 is given by:
Force at piston 2 = pressure × area
24,000 N = 6,00,000 × area
area = 0.04

Answer:
=24.25 ^−1
Explanation:
Let and be initial and final velocity of the body respectively,
be acceleration due to gravity ( 9.8^−2 ), ℎ be the height of the body.
=0 ^ −1
ℎ=30
we know that, ^2−^ 2=2ℎ
^2=2∗9.8∗30
^2=588
=24.25 ^−1
