Answer:

The work done to lift the counterweight equals the potential energy acquired

Explanation:

since this is vertically applied force on the counterweight, and the distance the force is displacing the counterweight is in the same direction as the applied force, it equals the gained potential energy

A wire carries a current of 0.66 A. This wire makes an angle of 58° with respect to a magnetic field of magnitude 5.50 10-5 T. T

Oliga [24]

Answer:

The length of the wire is "1.93 m".

Explanation:

Given:

Current,

I = 0.66 A

Angle,

$\Theta$ = 58°

Magnetic field of magnitude,

F = $5.5\times 10^{-5}$ N

The length of the wire will be:

⇒ $F = B\times I\times L\times Sin \Theta$

or,

⇒ $L = \frac{F}{B\times I\times Sin \theta}$

By putting the values, we get

$=\frac{5.5\times 10^{-5}}{0.66\times 5.1\times 10^{-5}\times Sin \ 58^{\circ}}$

$=\frac{5.5}{2.828}$

$=1.93 \ m$

How does a pith ball electroscope work

Mice21 [21]

Answer:

look at the explanation

Explanation:

This pith-ball electroscope is used to detect the presence of a static electricity charge. The two lightweight “pith” balls suspended from the strings are attracted to objects with a static electric charge. The pith balls can also be charged by touching them to an object with a static electric charge.
