Answer:
L = 0.109 H
Explanation:
Given that,
Number of loops in the solenoid, N = 1500
Radius of the wire, r = 4 cm = 0.04 m
Length of the rod, l = 13 cm = 0.13 m
To find,
Self inductance in the solenoid
Solution,
The expression for the self inductance of the solenoid is given by :
L = 0.109 H
So, the self inductance of the solenoid is 0.109 henries.

Explanation:
The impulse is defined as the change of momentum:
We took the final velocity as negative since it is going on the opposite direction of the intial motion of the ball.
Answer:
1).
2). Toward us
3).
4). Toward us
5).
6). Away from us
7).
8). Away from us
Explanation:
Spectral lines will be shifted to the blue part of the spectrum if the source of the observed light is moving toward the observer, or to the red part of the spectrum when it is moving away from the observer (that is known as the Doppler effect).
The wavelength at rest is 121.6 nm ()
Then, for this particular case it is gotten:
Star 1:
Star 2:
Star 3:
Star 4:
Star 1:
Toward us
Star 2:
Toward us
Star 3:
Away from us
Star 4:
Away from us
Due to that shift the velocity of the star can be determine by means of Doppler velocity.
(1)
Where is the wavelength shift,
is the wavelength at rest, v is the velocity of the source and c is the speed of light.
(2)
<em>Case for star 1 :</em>

Notice that the negative velocity means that is approaching to the observer.
