Suppose the amount of radiation that could be received from a microwave oven varies inversely as the square of the distance from it. How many feet away must you stand to reduce your potential radiation exposure to the amount you could receive standing 1 foot away?

How loud is a jet?
A jet at 100 m distance can have a sound pressure level of L = 140 dBSPL.Never forget to tell the distance of the measuring microphone from the sound source, because the closer you are the louder it is.The sound pressure level decreases by 6 dB per doubling of distance from the source to 1/2 (50 %) of the sound pressure initial value.The sound pressure decreases inversely as the distance increases with 1/r from the sound source.
Can radio waves be polarized?
Yes, like all electromagnetic radiation can be polarized. The A. T. & T. Long Lines Microwave tower system doubled its long distance call capacity by using cross polarized microwaves. This system operated from the late 1940s to the early 1990s (when fibre optics superceded it, but many of the towers and horns remain, see the image above showing a transmitting/receiving pair of horns).
Are gamma rays and radio waves the most dangerous waves?
Gama rays and radio waves together with the light for example are all electromagnetic waves. The properties of the waves depends on the frequency. If they have higher frequency, the have also higher energy which could be absorbed by body. This list shows electromagnetic spectrum. The waves are ordered from the lowest frequency to highest, which is the most dangerous. - radio - microwave - infrared - visible - ultraviolet - x-ray - gama rays However, the distance from the source of the radiation is important. That's why are scientists arguing about the harmfulness of mobile phones. On the other hand, well protected and shielded nuclear power plant is absolutely harmless.
How are radio waves and microwaves alike?
Their frequencies are quite different. Microwaves are electromagnetic radiation with frequencies in the range from 300 MHz (0.3 GHz) to 300 GHz. Ultraviolet rays are electromagnetic radiation with wavelengths in the range from 10 nm to 400 nm (frequencies from 2.99x107 to 7.5x105 GHz). Since the frequencies are so different, UV filters may not filter microwaves and vice-versa. Similarly, absorption of the two forms of radiation is quite different. Microwaves can heat a cup of soup up very nicely while you could die of starvation waiting for UV rays to heat it up.
How does the draw weight on a bow affect the distance of an arrow?
Not exactly sure but i believe when you pull back on the bowstring your giving it more potential energy that, when released, transfers more kinetic energy to the arrow allowing it to fly farther.
What two factors of the electromagnetic radiation have an inverse relationship?
The intensity of any electromagnetic radiation is inversely proportional to the square of the distance of the emitter of that radiation.
How does distance affect intensity of radiation?
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.
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.
Is gravity and distance conversely proportional?
No. The word is "inversely", not "conversely". And the force of gravity is inversely proportional to the square of the distance.
Offer a rationalization why the Bjerrum length is inversely porportional to temperature?
The Bjerrum length is the separation distance at which the potential electric energy of two elementary charges is equal to kB*T. The electric potential energy of two elementary charges is inversely proportional to their separation distance. Since kB*T is trivially proportional to temperature T, at a higher temperature you need to place two elementary charges closer to each other to get the electric potential energy equal to kB*T. As the separation distance between those charges is defined as the Bjerrum length, the Bjerrum length is inversely proportional to temperature.
What type of relationship does increased distance and decrease gravity show?
Inversely proportional
Which statement is true of the relationship between distance and gravity?
inversely proportional
How much is gravity reduced as distance increases?
Gravity is inversely proportional to the square of the distance.
Explain how the gravitational force between objects changes when the distance?
The gravitational force is inversely proportional to the square of the distance. For example, if you increase the distance by a factor of 10, the force will decrease by a factor of 100 (10 squared).The gravitational force is inversely proportional to the square of the distance.

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.

What is the realashionship between the force of gravity and distance?
Force due to gravity is inversely related to the square of the distance.
Are speed and distance directly proportional or inversely proportional?
Directly proportional. Greater speed - greater distance.
