What is a physical factor?
A physical factor is any element or influence in the environment that is tangible and can have an impact on living organisms or non-living things. This can include factors such as temperature, light intensity, humidity, and soil composition.
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.
How does intensity work?
In general, intensity refers to the amount of energy or power carried by a wave. In the context of sound and light, intensity is proportional to the square of the amplitude of the wave, meaning that doubling the amplitude increases the intensity by a factor of four. Intensity is measured in watts per square meter.
What is physical factor?
A physical factor refers to a characteristic or element that is related to the physical aspects of a system, organism, or environment. These factors can include temperature, light intensity, pressure, and humidity, among others, and they can have direct impacts on biological processes and ecological interactions. Understanding and managing physical factors are essential in fields such as biology, ecology, and environmental science.
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 a relationship between intensity and decibel?
Intensity is a physical quantity that measures the amount of energy per unit area, while decibel is a logarithmic scale used to express the relative intensity of a sound compared to a reference level. The relationship between intensity and decibel is non-linear; an increase in intensity by a factor of 10 corresponds to an increase of 10 decibels.
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.
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 describes any physical phenomenon that varies inversely with the square of the distance from the source?
Any physical phenomenon that varies inversely with the square of the distance from the source follows the inverse square law. This means that as the distance from the source doubles, the intensity or strength of the phenomenon decreases by a factor of four. Examples include the intensity of light, gravity, and electromagnetic radiation.
Can mode-1 stress intensity factor be negative?
No. Never.
