Answer:
Explanation:
From the question we are told that
Pressurized air pressure is 
Atmospheric pressure is 
Initial acceleration of the water rocket is 
Acceleration of the water rocket is 
Mass of water is 
Generally total mass is given mathematically given as
Generally the tension on the rocket is given mathematically given as
T is also
Therefore
therefore diameter of nozzle is mathematically given as
Answer:
The force of impact of the water bottle is F = 13,475 N
Explanation:
Given data,
The height of the antenna, h = 275 m
The mass of the 1 L water bottle, m = 1 kg
Let the bottle moves distance immediately after the impact is, d = 0.2 m
The force exerted by the bottle on the bushes at the ground is given by the formula,
F = mgh / d
Substituting the values
F = 1 x 9.8 x 275 / 0.2
= 13,475 N
The value of the force of impact can be reduced by increasing the value of d, it is like the lowering the hand along with the motion of the ball to catch it thereby reduce the force of impact.
The force of impact of the water bottle is F = 13,475 N
I would say its c
given a fixed volume, when volume decreases while mass remains constant
density increases ie temperature increases also
Answer:
If something is traveling at a constant velocity, then forces are balanced.
Explanation:
If something is traveling at a constant velocity, then the forces must be balanced because a constant velocity is only achieved with balanced forces.
