If the strength of a magnetic field at B is three units the strength of the magnetic field at A, means that point B has three times more turns as compared to point A.
<h3>How strength of the magnetic field should be increased?</h3>
We can increase the strength of the magnetic field by increasing the number of turns which increases the strength of the current flow.
So we can conclude that point B has three times more turns as compared to point A.

The average it the constant speed.
Explanation:
The high hardness of quartz, seven on the Mohs Scale, makes it harder than most other natural substances. As such it is an excellent abrasive material. Quartz sands and finely ground silica sand are used for sand blasting, scouring cleansers, grinding media, and grit for sanding and sawing
Answer:
0.421 cm
Explanation:
Volume of a cylinder is:
V = πr²h
where r is the radius and h is the height or length.
Given V = 1.932 cm³ and h = 3.47 cm:
1.932 = πr² (3.47)
0.557 = πr²
r² = 0.177
r = 0.421
The radius is 0.421 cm.
