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)²
I2 = I1 * (1/3)² = I1 / 9
Three times farther away gives one ninth the sound intensity of the close sound intensity.

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.
How does the intensity of a sound wave change if the distance from the source is reduced by a factor of 3?
The intensity of a sound wave would increase by a factor of 9 (3^2) if the distance from the source is reduced by a factor of 3. This is because intensity is inversely proportional to the square of the distance from the source.
How does the electric force change between two positive charges when the distance between the charges is tripled?
The electric force between two positive charges will decrease by a factor of 9 (inverse square law) when the distance between the charges is tripled.
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 decreased by a factor of 2?
The intensity of a sound wave is inversely proportional to the square of the distance from the source. If the distance from the source is decreased by a factor of 2, the intensity increases by a factor of 2 squared, which is 4. Thus, the sound intensity becomes four times greater as the distance is halved.

The electric force between two positive charges will decrease by a factor of 9 (inverse square law) when the distance between the charges is tripled.
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.
What will happen to the force of gravity if the mass of one of the objects is tripled?
You didn't specify what force. some forces have an inverse-square relationship. That is to say, the force of gravity, or electrostatic attraction or repulsion, is inversely proportional to the square of the distance - if the distance is tripled, the force is reduced by a factor of 9.You didn't specify what force. some forces have an inverse-square relationship.

The gravitational force between two masses is 36 N. What is the gravitational force if the distance between them is tripled?
If the distance between the two masses is tripled, the gravitational force between them will decrease by a factor of 9 (1/3)^2. Therefore, the gravitational force will be 4 N.
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).
