Answer:
I think it would be C: open primary
Explanation:
Answer:
Weight
Weight ( ) is a force, measured in newtons ( ). Weight is caused by the pull of gravity acting on a mass, usually near the surface of a planet.
Explanation:
Answer:
Potential energy
Explanation:
Given data
Weight of the person = 1000 N
Mass of the person = 
Speed = 6.26 
Kinetic energy is given by

Put the values in above formula we get


When the person reach top point then at this point the velocity is zero & kinetic energy at top point is equals to the potential energy.
Therefore potential energy
1) hypothesis
2) data
3) method
I think these are correct.
Answer:

Explanation:
As we know that the force due to propeller when it will push the water backwards is given as

now we know that

so we have



here we know that



now the force is given as


now the acceleration of the ship is given by Newton's II law
