Answer:
we have formula of frequency :
frequency(f)= speed of sound(c)/wavelength(λ)
for wavelength we swipe it with frequency as follows
λ=c/f
λ=300,000,000/101,700,000
λ=2.949
Answer:
Given
mass (m) =2kg
velocity (v) =3m/s
momentum (p) =?
Form
p=mv
2kgx3m/s
p=6kg.m/s
the momentum of ball's =6kg.m/s
The volume of water will increase . If yu subtract the original volume from the new volume of water you will get the volume of the small ball.
Answer:
I would agree with the statement. it's not just the body, but everything that we see is almost 99.9999% empty space
