Answer : The correct answer for both the fill in the blank is, increases.
Explanation :
Formula used :
1)
B = strength of magnetic filed
N = Number of loops
I = current in the wire
= magnetic permeability
The more the number of loops in the solenoid more will the strength of three magnetic fields.
2) Also according to Ohm's law:
Voltage is directly proportional to current:
With increase in voltage the the current will increase which in return increase the magnetic field in the solenoid.
So, the correct answer for both the fill in the blank is, increases.

Answer:
b. Jupiter’s greater gravity has compressed the layers, so they are closer together there.
Explanation:
The value for Jupiter mass is 1.8981×10²⁷kg, while the mass of Saturn is 5.6832×10²⁶kg, so the different layers of clouds in Jupiter will be submitted to a greater gravitational pull because it has a bigger mass, as is established in the law of universal gravitation:
(1)
Where m1 and m2 are the masses of two objects, G is the gravitational constant and r is the distance between the two objects.
As it can be seen in equation 1, the gravitational force is directly proportional to the product of the masses of the objects, so if the mass increase the gravitational force will do it too.
For the case of Saturn, it has a lower mass so its layers of clouds will suffer a weaker gravitational pull. That leads to the three clouds being more spacing that the ones of Jupiter.
