Answer:
In order to shoot an arrow with a bow, you should hold the bow with your left hand, and should pull the string to yourself and stay for a moment to aim.
At that point your arm applies a force, and that force does work on the bow. This work is stored as elastic potential energy. When you release the arrow, this potential energy is converted to kinetic energy, in this way the arrow is thrown forward.
This is the simplified version. Of course, in real life the case is different.
In real life, when you hold the string to aim, there is elastic potential energy, and also gravitational potential energy to hold the arrow above the ground. When you release the arrow, it goes through the side of the bow with a friction. So, part of the potential energy is converted to heat when the arrow and bow is still in contact. After they lose contact, the potential energy is converted to kinetic energy, and the motion of the arrow is projectile, since the arrow both moves forward and downwards. Eventually the arrow hits the ground.
Answer:
The correct answer is - option D. managing emotions.

Answer:
The gravitational force is related to the mass of each object.
The gravitational force is an attractive force.
Explanation:
Gravitational force is a long range force of attraction between any two masses.
Mathematically given as :
where:
are the masses
r= distance between the center of mass of the two objects.
G= gravitational constant = 
From the above relation of eq. (1) it is clear that,
Gravitational force is inversely proportional to the square of the distance and directly proportional to the masses.
The mass of an object is independent of its size due to the fact that density may vary for different objects.
The force of gravity varies with height as:
where:
gravity at height 
of the center of mass of the object from the center of mass of the earth.
and we know that force:
where: m= mass of the object.
