Discuss what in particular makes the light bulb a non-ohmic resistor. Specifically, how does temperature affect resistance? Can

bagirrra123 [75]

Answer:

the loss of energy due to the Joule effect is the cause of the non-ohmic characteristic of the bulb

Explanation:

A resistance is formed of some type of metal, in a light bulb it is Tungsten, which for low current is a resistance that complies with the ohm law.

When the value of the current is increased the shock of the electors creates a Joule effect, which heats the metal, these shocks are due to atomic imperfections of the structure, this heating creates a loss of energy of the system that causes the characteristic to be lost linear between the voltage and the current, since the total energy balance must be preserved.

An approximate measure of the energy that is emitted is given by Stefan's law.

In short, the loss of energy due to the Joule effect is the cause of the non-ohmic characteristic of the bulb

A student whirls a rubber stopper attached to a string in a horizontal circle above her head. If the radius of the stopper in ci

alexandr402 [8]

Answer:

$v = 12.57 m/s$

Explanation:

As we know that the radius of the circular motion is given as

$R = 50.00 cm$

time period of the motion is given as

$T = 0.2500 s$

now we know that it is moving with uniform speed

so it is given as

$v = \frac{2\pi R}{T}$

now plug in all data

$v = \frac{2\pi(0.50)}{0.25}$

$v = 12.57 m/s$

What is the difference between pitch and volume?

Fantom [35]

Answer:

Pitch is a measure of how high or low something sounds and is related to the speed of the vibrations that produce the sound. Volume is a measure of how loud or soft something sounds and is related to the strength of the vibrations.
