If the distance from the light source is tripled how much does the light intensity change?
The light intensity decreases by a factor of nine when the distance from the light source is tripled. This relationship is governed by the inverse square law, which states that the intensity of light is inversely proportional to the square of the distance from the source.
What is magnitude of 12 N if distance is reduced by factor of 2?
It depends on the situation. If you mean the gravitational force, or the electrical force, between two objects, reducing the distance by a factor of 2 will increase the force by a factor of 4.
How does the electric potential energy between two positive charged particles change if the distance between them is reduced by a factor of 3?
The electric potential energy between two positive charged particles will increase by a factor of 9 (3 squared) if the distance between them is reduced by a factor of 3. This is because the potential energy is inversely proportional to the distance between the charges squared.
How is the intensity of light and distance related?
The intensity of light decreases as distance from the source increases. This relationship follows an inverse square law, meaning that if you double the distance from the source of light, the intensity decreases by a factor of four.
What happens to the light intensity if you half the distance to the source?
The light intensity increases by a factor of four when you half the distance to the source. This is known as the inverse square law, where light intensity is inversely proportional to the square of the distance from the source.
How does the intensity of a sound wave change if the distance from the source is reduced by a factor of 4?
- 6 dB is incorrect. It will decrease by 12 dB.
How does the intensity of a sound wave change if the distance from the source increases by a factor of 2?
The intensity increases by a factor of 4-APEX
How does intensity vary with distance from the source?
It's an inverse-square law - for instance, double the distance, and the intensity will be reduced by a factor 1/4.This assumes that there is nothing absorbing the light (for instance, fog); if there is, the intensity in the above example will of course be even less than 1/4 the original intensity.

Does distance important on gravitational strength field?
Yes. The gravitational force is inversely proportional to the square of the distance; meaning, for example, that if you increase the distance by a factor of 10, the force will be reduced by a factor 100.Yes.

By what factor will the sound of a source change the intensity of the waves if the distance is tripled from the sound source?
For sound intensity (acoustic intensity) we use in the free field (direct field) the inverse square law = 1/r². I1 and r1 belong to the close distance and I2 and r2 belong to the far distance.I2 = I1 * (r1/r2)²I2 = I1 * (1/3)² = I1 / 9Three times farther away gives one ninth the sound intensity of the close sound intensity.
Tripling the distance from a constant intensity point will cause the illumination to?
Decrease by a factor of 9. The illumination at a point is inversely proportional to the square of the distance from the source. By tripling the distance, the intensity will decrease by 9 times (3^2 = 9).
How does the electric potential energy between two positively charged particles change if the distance between them is reduced by a factor of 3?
The electric potential energy between two positively charged particles increases by a factor of 9 if the distance between them is reduced by a factor of 3. This relationship is based on the inverse square law, where potential energy is inversely proportional to the square of the distance between charged particles.
