Answer:
They will rotate twice as fast
Explanation:
Angular momentum is product of
m= mass,
v=velocity
and
r= radius.
i-e
Angula Momentum = m×v×r=mvr
<u>If we increase mass</u>
Here we replace m with 2m and keep the size same i-e radius is kept constant !
==> Angular Momentum = 2m×v×r=2mvr
Answer:
New force, 
Explanation:
The electrostatic force between two spheres is given by :
According to given condition, each of the spheres has lost half its initial charge, new force is given by :
So, the new force becomes (1/4)th of the initial force. Hence, the correct option is (d).
Explanation:
The law of conservation of energy is one of the fundamental laws of science that helps to understand energy in nature.
Energy is the ability to do work. There are different forms of energy.
Generally, energy is classified into potential and kinetic forms of energy. Potential energy is the energy at rest in a body. It is due to the position of the body.
Kinetic energy is the energy due to the motion of a body.
There are different forms of kinetic and potential energy and they are related by the law of conservation of energy.
The law states that "in an isolated system, energy is neither created nor destroyed by transformed from one form to another".
An isolated system is a system in which there is no exchange of matter and energy.
Due to this we know that no new energy is created or destroyed, they are only transformed from one form to the other.

<h2>Answer:</h2>
Phytochemicals are compounds that are produced by plants ("phyto" means "plant"). They are found in fruits, vegetables, grains, beans, and other plants. Some of these phytochemicals are believed to protect cells from damage that could lead to cancer.
When talking about orbits, it would have to be a mixture of both A. and B. since Newton's first law, gravity plays a huge part in an orbit. However, the universal gravitation law also tells us the relationship between two massive objects in orbit. But to choose only one, it would have to be B. Newton's first law
