A long, thin solenoid has 155 turns per meter and radius 1 m. The current in the solenoid is increasing at a uniform rate of 28
A/s.
What is the magnitude of the induced electric field at a point 9.5 m from the axis of the solenoid?
Express your answer in mV/m to 2 decimal places.

Answer:
You will hear the note E₆
Explanation:
We know that:
Your speed = 88m/s
Original frequency = 1,046 Hz
Sound speed = 340 m/s
The Doppler effect says that:
Where:
f = original frequency
f' = new frequency
v = velocity of the sound wave
v0 = your velocity
vs = velocity of the source, in this case, the source is the diva, we assume that she does not move, so vs = 0.
Replacing the values that we know in the equation we have:
This frequency is close to the note E₆ (1,318.5 Hz)
Answer:
A.2.95 m
B.7
Explanation:
We are given that
Diffraction grating=600 lines/mm
d=
Wavelength of light,
l=4.6 m
A.We have to find the distance between the two m=1 bright fringes
For first bright fringe, =1
The distance between two m=1 fringes
Hence, the distance between two m=1 fringes=2.95 m
B.For maximum number of fringes,
Substitute the values
Maximum number of bright fringes on the scree=
