Static charge builds on anon moving object so the charges in a conductor are moving so it cannot build up

Because it is conducted away IF the conductor is connected to earth;otherwise as the first feller said it will remain where it is and act as in a capacitor.Example is in the gold leaf electroscope where two gold pieces of gold leaf with the same charge visibly separate from one another;but if the electroscope is earthed the charges disappear and the leaves fall back into contact.As to hospital operating theatres such a spray of fine droplets would be attracted to surfaces especially if they were
<span>charged and would kill germs in unreachable places.A bit like electrostatic painting of car bodies during manufacture where the paint drops ae electrostatic-ally drawn to all surfaces of a car body which is at high voltage of electrostatic charge. hope that helped</span>

describe the motion of objects that are viewed from your reference frame both inside and outside while you travel inside a movin

V125BC [204]

Answer:

The objects outside the reference frame aren't moving. It appears this way since the vehicle you are inside is moving, but unless the objects are people, animals, or other vehicles, the objects aren't moving.

Why is a spectrum of colors produced when white light passes through a prism?

Mkey [24]

Explanation: White light is all colors of light in one, so when white light passes through a prism, the light gets refracted and breaks apart into all of the colors on the visible light spectrum.

An old light bulb draws only 54.3 W, rather than its original 60.0 W, due to evaporative thinning of its filament. By what facto

Lemur [1.5K]

Answer:

The factor of the diameter is 0.95.

Explanation:

Given that,

Power of old light bulb = 54.3 W

Power = 60 W

We know that,

The resistance is inversely proportional to the diameter.

$R\propto\dfrac{1}{D}$

The power is inversely proportional to the resistance.

$P\propto\dfrac{1}{R}$

$P\propto D^2$

We need to calculate the factor of the diameter of the filament reduced

Using relation of power and diameter

$\dfrac{P_{i}}{P_{f}}=\dfrac{D_{i}^2}{D_{f}^2}$

Put the value into the formula

$\dfrac{D_{i}^2}{D_{f}^2}=\dfrac{54.3}{60}$

$\dfrac{D_{i}}{D_{f}}=0.95$

$D_{i}=0.95 D_{f}$

Hence, The factor of the diameter is 0.95.
