There are some methods that differentiate waves; one thing is by its medium.
Electromagnetic waves did not require a medium for transmission such as in a
vacuum while mechanical waves require a medium to travel such as air, water or
anything that can serve as a transmission aid.
The most common sample of EM waves in
telecommunication is radio,
light and infra-red signals. An example of a mechanical wave is a sound
wave, which requires air to travel. Oscillating molecules made the
sound waves.
I did the math and i got 450 but i dont know if its right
1) Option b: gas pressure.
This is sustainted by the kinetic molecular theory of the gases.
2) Option c: raising the temperature of the gas will increase the pressure if the volumen of the gas and the number of particles are constant.
PV = nRT
If V and n are constant, P is proportional to T, then if T increase P will increase too.
The answer B. Fats and proteins are molecules with many chemical bonds; the bonds release much energy when broken. Typically, our bodies would use the fat for energy. Proteins are used to build and run (enzymes) our body. But they can still be used as a source of chemical energy.
Answer:
Researchers use speculations to create innovations or discover a remedy for an ailment. Some feel that speculations become laws, yet hypotheses and laws have isolated and particular jobs in the logical strategy. A law is a portrayal of a watched marvel in the common world that remain constant each time it is tried.
