Explanation:
Given
Wooden board is pivoted at center and
Older child of mass 
is sitting at a distance of L from center
if two child of mass 
is sitting at a distance 
and 
(say) from pivot then net torque about pivot is zero
i.e.
as 
Therefore
Therefore another child is sitting at a distance of
Explanation:
When a radioactive substance decays then the fast moving electrons emitted by it is known as beta ray. Basically, a number of beta particles are ejected by a beta ray.
Symbol of a beta particle is 
. A beta ray is a natural decay of a radioactive element. As we know that opposite charges get attracted towards each other. So, a beta ray gets attracted towards a positively charged plate.
Therefore, we can conclude that following are the characterizes a beta ray:
- a product of natural radioactive decay.
- is attracted to the positively charged plate in an electric field.
- is composed of electrons.
Current = charge/time = 240/2x120 =1A.
Current flowing is 1 ampere.
The channel is whatever was used to carry information from
one place to another, or from one person to another.
In this scenario, the channel is e-mail.
