Milky way doesnt have planets oribting arount the sun like our solarsystem.
Answer:
(a) 9.65 mH
(b) doubled
Explanation:
A = 6 cm^2 = 6 x 10^-4 m^2, l = 20 cm = 0.2 m, i = 2.8 A, N = 1600
(a) The formula for the self inductance of a solenoid is given by
L = μ0 N^2 A / l
L = 4 x 3.14 x 10^-7 x 1600 x 1600 x 6 x 10^-4 / 0.2
L = 9.65 x 10^-3 H
L = 9.65 mH
(b) As we observe that the inductance is proportional to the area so if the area is doubled, then inductance is also doubled.
147.09975 newton meters per second
It will take 2.77..... seconds
Using the wavelength expressions, such as the distance between two peaks of a wave, that of the frequency as a function of the speed and the wavelength, such as the period inversely proportional to the frequency we have to for the first question
the wavelength is the distance between the two ridges that is
For the second question the frequency is determined as the rate of change of the velocity versus the wavelength, that is
For the third question the period is inversely proportional to the frequency, therefore
