Answer:
The fundamental resonance frequency is 172 Hz.
Explanation:
Given;
velocity of sound, v = 344 m/s
total length of tube, Lt = 1 m = 100 cm
height of water, hw = 50 cm
length of air column, L = Lt - hw = 100 cm - 50 cm = 50 cm
For a tube open at the top (closed pipe), the fundamental wavelength is given as;
Node to anti-node (N ---- A) : L = λ / 4
λ = 4L
λ = 4 (50 cm)
λ = 200 cm = 2 m
The fundamental resonance frequency is given by;
Therefore, the fundamental resonance frequency is 172 Hz.
Answer:
Part a)
Moment of inertia of the cylinder is given as
Part B)
Height of the cylinder is of no use here to calculate the inertia
Part C)
Since we don't know about the viscosity data of the soup inside the cylinder so we can't say directly about the moment of inertia of the cylinder as
Explanation:
As we know that the inclined plane is of length L = 3 m
and its inclination is given as 25 degree
so we know that acceleration of center of mass of the cylinder is constant so we will have
so we have
now we know that
Now we have know that final speed of the cylinder due to pure rolling is given as
Part B)
Height of the cylinder is of no use here to calculate the inertia
Part C)
Since we don't know about the viscosity data of the soup inside the cylinder so we can't say directly about the moment of inertia of the cylinder as

Answer:
north
Explanation:
When a charged particle moves in a magnetic field, the particle experiences a force given by the formula:
where
q is the magnitude of the charge
v is its velocity
B is the magnetic field
is the angle between the directions of v and B
In this problem,
(charge of the electron)
(strength of magnetic field)
(force)
Therefore, the velocity is
The direction of the force is perpendicular to both the direction of the velocity and the magnetic field, and it can be found using the right-hand rule:
. Thumb: direction of the force (downward) --> however the charge is negative, so this direction must be reversed: upward
- Middle finger: direction of the field (west)
- Index finger: direction of velocity --> north
So, the electron is travelling north.
