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 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.
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).
If the distance between us and a star is doubled the apparent brightness is decreased by a factor of four true or false?
True. The apparent brightness of a star is inversely proportional to the square of the distance between the star and the observer. So if the distance is doubled, the apparent brightness will decrease by a factor of four.
Which factor affects most in transpiration-humidity or light intensity?
Light intensity
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 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 gravitational force change if distance decreased by half?
The gravitational force then increases by a factor of 4 .
How does the electric force between two charged particles change if the distance between them is decreased by a factor of 3?
The electric force between two charged particles is inversely proportional to the square of the distance between them. If the distance is decreased by a factor of 3, the electric force will increase by a factor of (1/3)^2 = 1/9. This means the force will increase by a factor of 9 when the distance decreases by a factor of 3.
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.
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 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.
Find the change in the force of gravity between two planets when the distance between them is decreased by a factor of five?
it will increase by a factor of 25.since F= G . M m/ d2 thus when the distance decrease by a factor of five i.e to fifth of the original distance the grvitational force will increase by 25 (1/5) 2 .
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.
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).
What external factor will most frequently change the viscosity of the motor oil?
decreased temperature
