Answer:
Explanation:
We name M the larger mas, and m the smaller mass, so base on this we write the following conservation of momentum equation for the collision:
We can write this in terms of what we are looking for (the quotient of masses :
We use now the information about Kinetic Energy of the system being reduced in half after the collision:
We can combine this last equation with the previous one to obtain:
where solving for the quotient m/M gives:
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate . this means that electromagnetic waves can travel not only through air and solid materials bit also through vacuum of space.
The smaller the displacement, the smallest restoring force it will create.
As seen from the figure given below, The spring system follows the equation,
F = -Kx
where, x is the displacement
F is the restoring force
k is the spring constant
If , K is kept constant, then,
F is directly proportional to the displacement but it acts in opposite direction due to negative sign.
