Answer:
Wave speed = 50 m
Explanation:
Given
Wavelength = 5 m
Frequency = 10 Hz = 10
wave speed = ?
We know that all waves have same relationship among wavelength λ, frequency f and speed v , which is given by
v = fλ
Therefore wave speed = 10 x 5 m = 50 m
A) travel outside the necleus
Answer:
Elastic collision
Explanation:
The interaction of two particles is called collision. There are two types of collision i.e. elastic collision and inelastic collision.
Two bouncy balls colliding with each other is an example of elastic collision. In this type of collision the momentum and kinetic energy of the bodies remains constant i.e.
and
Where
m₁ and m₂ are masses of two balls A and B
u₁ and u₂ are initial velocities of ball A and B
v₁ and v₂ are final velocities of ball A and B
