Adevice is turned on and 2.60 a flows through it 0.170 ms later. what is the self-inductance of the device (in mh) if an induced 160 v emf opposes this?

Self inductance of the device is 10.4 mH.

Explanation:

It is given that,

Change in current,

Time,

Induced EMF, E = 160 V

Let L is the self inductance of the device. It is given by :

L = 0.0104 H

or

L = 10.4 mH

So, the self inductance of the device is 10.4 mH. Hence, this is the required solution.

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

not too sure thinking all accelerations are pointed down
