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.
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 between the masses would increase by a factor of 4 (1/d^2), where d is the distance between the spheres. This is because the force of gravity is inversely proportional to the square of the distance between the masses.
Which factor affects most in transpiration-humidity or light intensity?
Light intensity
How far would you have to be to get a reading of 60 dB when standing outside 15 m away from a boombox the intensity level was measured at 80 db?
To achieve a reading of 60 dB, you would need to be roughly 30 meters away from the boombox. Sound intensity decreases with the square of the distance from the source, so increasing the distance by a factor of √(80 dB - 60 dB) = √20 results in the required change in distance (15 m x √20 ≈ 30 m).
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.
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.
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 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.
What is the relationship between wave amplitude and intensity?
Wave intensity is directly proportional to the square of the wave amplitude. This means that as the wave amplitude increases, the wave intensity increases by a larger factor. In other words, a small change in wave amplitude can result in a significant change in wave intensity.
When a sounds intensity increases by a factor of 10 its decible reading increase by?
When a sound's intensity increases by a factor of 10, its decibel reading increases by 10 dB, following a logarithmic scale. This means that for every 10-fold increase in intensity, the decibel level increases by 10 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.
When a sounds intensity increases by a factor of 10 its decibel reading increases by what?
When a sound's intensity increases by a factor of 10, its decibel reading increases by approximately 10 decibels. This is because the decibel scale is logarithmic, with each 10-fold increase in intensity equating to a 10 dB increase in perceived loudness.
How does gravitational force change if distance decreased by half?
The gravitational force then increases by a factor of 4 .
What is the relationship between the intensity of the radiation given off from a radiation source and distance from the radiation source?
The source doesn't care how far you are from it, or whether you're even there, andthere's no relationship between that and the intensity of the radiation it gives off.However, the intensity of the radiation that you receivefrom it is inversely proportionalto the square of your distance from it ... same math as for gravity.
By what factor will the sound of a source change the intensity of the waves if the distance is tripled from the sound source?
The intensity of the sound waves will decrease by a factor of 9 if the distance from the source is tripled. This is because intensity decreases with the square of the distance from the source due to the spreading out of the waves in a three-dimensional space.
