Answer:
Net force acting on them is 16 N and it is acting to the right side.
Explanation:
It is given that,
Force acting by the dog, (right side)
Force acting by Simone , (backward)
Let backward direction is taken to be negative while right side is taken to be positive.
The net force will act in the direction where the magnitude of force is maximum. Net force is given by :
F = 16 N
So, the net force is 16 N and it is acting to the right side.
Answer:
Explanation:
Given
Original Frequency
apparent Frequency
There is change in frequency whenever source move relative to the observer.
From Doppler effect we can write as
where
apparent frequency
v=velocity of sound in the given media
velocity of source
velocity of observer
here
i.e.fork acquired a velocity of
distance traveled by fork is given by
where v=final velocity
u=initial velocity
a=acceleration
s=displacement
