Physics
1 answer:
Sergeeva-Olga [200]3 years ago
6 0

Answer:

The correct option is (b).

Explanation:

The relation between the wavelength and frequency is given by :

\lambda=\dfrac{v}{f}

Where

v is the wave speed

f is the frequency of a wave

It is clear from the above equation that the wavelengths and frequency can vary inversely to produce the same wave speed.

A penny dropped into a wishing well reaches the bottom in 2.50 seconds. What was the velocity at impact?
12345 [234]

Answer:

Taking it was dropped with inital velocity of 0m/s.

v = u+at

v = 0 + 9.8*1.5

v = 14.7s

(a=9.8m/s^2 << That's the acceleration due to gravity)

The self inductance relates the magnetic flux linkage to the current through the coil. Calculate the self inductance L in units
Katen [24]

Answer:

Self inductance, L=127\ \mu H

Explanation:

It is given that,

Length of the coil, l = 5 cm = 0.05 m

Area of cross section of the coil, A=3\ cm^2=0.0003\ m^2

Number of turns in the coil, N = 130

The self inductance relates the magnetic flux linkage to the current through the coil and it is given by :

L=\dfrac{\mu_oN^2A}{l}

L=\dfrac{4\pi \times 10^{-7}\times (130)^2\times 0.0003}{0.05}

L = 0.000127 Henry

or

L=127\ \mu H

So, the self inductance of the coil is 127 microhenry. Hence, this is the required solution.
