Answer:
708.3 Hz
Explanation:
For an open-air column, like the empty can, the fundamental frequency is given by
where
v = 340 m/s is the speed of sound
L is the length of the column
In this problem, the length of the bottle is
L = 24 cm = 0.24 m
Therefore, the fundamental frequency is
Answer:
7557.875 J
Explanation:
Assumimg we need to find work done by the bullet on the gas
The work is found by integrating force over distance
W=
For the force in this problem we have
=
=7557.875 J
Answer:
649.8420 nm
Explanation:
We have given
we have to find unknown wavelength that is
The condition for constructive interference is
Where d is distance between slits is angle of emergence and n is order of maxima
Using constructive interference equation
---------eqn 1
---------eqn 2
On dividing eqn 1 by eqn 2
