Answer:
BI/BII = 1
Explanation:
The magnetic field due to a solenoid is given by the following formula:

where,
B = Magnetic Field due to solenoid
μ = permeability of free space
n = No. of turns per unit length
I = current passing through the solenoid
Now for the first solenoid:

For the second solenoid:

Dividing both equations:

here, no. of turns and the current passing through each solenoid is same:
n₁ = n₂ and I₁ = I₂
Therefore,

<u>BI/BII = 1</u>
Answer:
c. nine times as low.
Explanation:
Sound intensity is defined as the acoustic power transferred by a sound wave per unit of normal area to the direction of propagation:

Since the sound wave has a spherical wavefront of radius r, then the area is given by:

Here r is the distance from the source of the sound. Thus sound intensity decreases as:

Ok so basically I’m here for the points cuz I gotta quiz do in 10 minutes sorry
Letter B because it is gaining more potential energy as it SLOWLY climbs up the hill.
the less motion the more potential energy there is
