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
The acceleration due to gravity only points downward with magnitude g. The angle of the projectile doesn't matter.
Answer:
For empiricists like van Fraassen, the phenomena of physics are the appearances observed or perceived by sensory experience. Constructivists, however, regard the phenomena of physics as artificial structures generated by experimental and mathematical methods.
