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
Which factor affects most in transpiration-humidity or light intensity?
Light intensity
What is the factor to change pounds to kilograms?
The factor is 0.454
Gases kept at constant temperature if its temperature is change from 50 celsius to 100 celsius by what factor does the factor change?
The temperature factor increases to 1.1547, approx.
If the distance between the spheres is cut in half what is the force between the masses?
The force increases by a factor of 4. If we're talking about gravity, the gravitational force is a function of the masses and the square of the distance between them. As distance decreased by a factor of 2 (since it was cut in half), then the force increases by a factor of 2 squared, and that's 4. Gravitational force increases by a factor of 4 when distance between two gravimetrically attracted objects is decreased by a factor of 2 (cut in half).
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. 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.

Tripling the distance from a constant intensity point will cause the illumination to?
Decrease by a factor of 9
How does the electric force between two charged particles change if the distance between them is increased by a factor of two?
The electric force between two charged particles is inversely proportional to the square distance between them.Accordingly, it is reduced by a factor of 9
How does distance affect gravitional attraction of two objects?
For every doubling of distance, the "force of attraction" is reduced by a factor of four. For every halving of distance, the "force of attraction" is increased by a factor of four.
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.
An increase of 20 dB increases the sound intensity by a factor of?
A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.
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.
A sound that is perceived as twice as loud requires how much intensity?
Scroll down to related links and look at "Sound level change and the change of the respective factor of volume / loudness, sound pressure / sound intensity".
The force of gravity on a spacecraft some distance from the earth is 800N What would that force be if its distance to the earth's centre were one half as great?
gravitational attraction between two bodies conforms to an inverse square law, so the force applied to the spacecraft by the earth is proportional to one over the displacement squared in this case, one quarter squared is one sixteenth, so the force would be multiplied by one over one sixteenth, which is sixteen the force would therefore be 800 x 16 = 12800N
What does increasing distance between objects have on the gravitational attraction between them?
The force of gravitational attraction is inversely proportional to the square of the distance between the centers of mass of the objects. For example, if the distance increases by a factor of two, the attraction is reduced by a factor of four.
