Answer:
= 0.5 m/s²
Explanation:
- According to Newton's second law of motion, the resultant force is directly proportion to the rate of change of linear momentum.
Therefore;<em> F = ma , where F is the Force, m is the mass and a is the acceleration.</em>
<em>Thus; a = F/m</em>
<em>but; F = 5 N, and m = 10 kg</em>
<em> a = 5 /10</em>
<u>= 0.5 m/s²</u>
To solve this problem it is necessary to apply the concepts related to mutual inductance in a solenoid.
This definition is described in the following equation as,

Where,
permeability of free space
Number of turns in solenoid 1
Number of turns in solenoid 2
Cross sectional area of solenoid
l = Length of the solenoid
Part A )
Our values are given as,





Substituting,



PART B) Considering that many of the variables remain unchanged in the second solenoid, such as the increase in the radius or magnetic field, we can conclude that mutual inducantia will appear the same.
Answer: C
Explanation:
Bro this is common sense. Throw something across the room and watch it. It isnt going to be repulsed and fly up. It also isnt going to continue on forever. It will clearly fall and hit the ground
