Answer:
B, B (decreases, a clockwise)
Explanation:
Finally, the switch on the electromagnet is reopened. The magnitude of the external magnetic flux through the wire loop <u>decreases</u>, and there is <u>a clockwise</u>, current induced in the loop (as seen from the left).

SOLVED DOWN BELOW
Explanation:
In series the same current goes thru both resistors, equiv resistance is 200 ohms, then using ohms law
<em>I = 25/200</em>
<em>I= .125 amps or 125 ma</em>
__________
<em>R= r1 * r2 / r1 +r2</em>
<em>R= 100 * 100 / 100 + 100</em>
<em>R= 10000 / 200</em>
<em>R= 50 ohms </em>

Answer:
they stay shifted the same amount to the red
Explanation:
Redshift is given by
Where,
= Wavelength observed
= Wavelength emitted
Also
Transverse redshift is given by
v = Velocity of object
c = Speed of light =
So, if the velocity is constant the redshift remains the same
