Answer:
Both feel same magnitude force.
Explanation:
Given that
Mass of father = 100 kg
Mass of daughter = 50 kg
From the third law of Newtons :
Every action have it reaction in opposite direction.It means that if any object apply a force on the other object then first object also feel force of same magnitude but in opposite direction.
It means that both father and her daughter will feel same magnitude of same but in opposite direction.
Answer:
option (a)
Explanation:
Wavelength is defined as the distance traveled by the wave in one complete oscillation.
The number of oscillations completed in one second is called frequency.
The relation for the wave velocity is given by
wave velocity = frequency x wavelength

Answer:
The value is 
Explanation:
From the question we are told that
The amount of power delivered is 
The time taken is 
The wavelength is 
Generally the energy delivered is mathematically represented as
Where 
is the Planck's constant with value 
c is the speed of light with value 
So
=>
