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.
Tripling the distance from a constant intensity point will cause the illumination to?
Decrease by a factor of 9
What happens to the intensity of a wave if the amplitude decreases?
Intensity of a wave is proportional to the frequency squared and amplitude squared based on this formula; I=1/2pw^2A^2V where p is the density of the medium, w is the angular frequency and A is the amplitude and V is the wave velocity. So, everything else remaining constant, decreasing the amplitude will decrease a waves intensity. Example decreasing the the amplitude by a factor of 4 will decrease the wave intensity by a factor of 8.
How many times louder is a sound wave with a intensity of 83db than a sound wave with an intensity of 70db?
Use the definition of decibel. The factor can be calculated as is 10(83-70/10). = 101.3.
How many times louder is an 80 dB sound compared to a 40 dB sound?
1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.
Which test satisfies the time reversal test and factor reversal test?
Fisher's Index
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 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
Which event illustrate the interaction of an abiotic factor with a biotic factor in the environment?
The low light intensity of the forest affects the growth of pine trees. The light intensity is an abiotic factor, the growth of pine trees is the biotic factor. This is your answer.
What are synonyms of multiplication?
product , multiply also, division reversal times, factor, and of!
Can mode-1 stress intensity factor be negative?
No. Never.
What is the most important exercise factor for achieving training effects?
Intensity
If the energy carried by a sound wave is multiplied by a thousand times bywhat factor does the intensity of the sound wave increase?
The factor does the intensity of the sound waves increase because the intensity of sound waves is related to the amplitude. Sound with a greater amplitude also has a greater intensity.
What is critical in stress intensity?
Stress intensity is related to product of stress and flaw size for materials. If stress is increased to critical, this results in catastrophic failure. The critical stress intensity factor KIc is a property of the material. KIc = Strength x sqrt(flaw) x geometry factor
Tripling the distance from a constant intensity point will cause the illumination to?
Decrease by a factor of 9
The volume and intensity of use that can be sustained in a particular place and time is called?
load factor
