Answer:
5541Hz
Explanation:
If the frequency of a wave is directly proportional to the velocity we have;
F = kV where;
F is the frequency
K is the constant of proportionality
V is the velocity
Since f = kV
K = f/v
K = F1/V1 = F2/V2
Given f1 = 412Hz v1 = 25.8m/s f2 = ? V2 = 347m/s
Substituting in the formula we have;
412/25.8=f2/347
Cross multiplying
25.8f2 = 412×347
F2 = 412×347/25.8
F2 = 5541Hz
The frequency heard will be 5541Hz
Answer:
According to Newtons 2nd law of motion ;
The acceleration an object experiences is as a result of the net force which is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Explanation:
This law is simply saying ;
Force = Mass ×Acceleration
I Hope It Helps :)
As we know that force F makes an angle of 60 degree with X axis
so the X component is given as
now we have
Similarly we know that force F makes an angle of 45 degree with Y axis
so the X component is given as
now we have
Now for the component along z axis we know that
now plug in all components
An antinode must occur at B, the open end of the pipe
Explanation:
For the standing waves produced in a pipe, open and closed ends reflect waves in a different way, so their behaviour is different. In particular:
- A closed end acts as a node (because there is no vibration of the wave)
- An open end acts as an antinode (maximum vibration of the wave)
This means that for the pipe in this problem:
A (the closed end on the right) must act as a node of the standing wave
B (the open end on the left) must act as an antinode of the standing wave
Therefore the correct answer in this problem is that an antinode must occur
at B, the open end of the pipe
