How will the behavior of the gases in the piston chamber change if more pressure is applied to the piston?

2 answers:

6 0

Here molecules of gas remains constant. If more pressure is applied to the piston, gaseous molecules will come closer to each other. Hence their volume decreases and density increases. Hope this helps you.

The answer is D.

The gas particles will hit the walls more frequently. Because more pressure is applied, the container will shrink in size. When this happens, the particles have less space to move and will hit the walls of the container more frequently, exerting more pressure.

The speed of sound is 346m/s if a sound wave travels at a frequency of 55hz what would it’s wavelength be

algol [13]

Answer:

6.29 m

Explanation:

The speed of a wave is equal to frequency times wavelength, so to find wavelength you'd have to divide frequency by both sides, speed(346) divided frequency(55) = 6.29 m

I'm not so sure about this let me know if I'm wrong

Even in the most advanced circuits, we cannot oscillate electrons back and forth at that rate through wires. But we can oscillat

den301095 [7]

Answer:

the oscillations of the electrons must be in the 10⁸ Hz = 100 MHz range

Explanation:

The speed of a wave of radio, television, light, heat, all are manifestations of electromagnetic waves that are oscillations of electric and magnetic fields that support each other, the speed of all these waves is the same and the vacuum is equal to c = 3 108 m / s

All waves have a relationship between the speed of the wave, its frequency and wavelength

c = λ f

f = c /λ

for this case lam = 1 m

f = 3 10⁸/1

f = 3 10⁸ Hz

the oscillations of the electrons must be in the MHz range

It should be clarified that the speed of light in air is a little lower

n = c / v

v = c / n

the refractive index of vacuum is n = 1 and the refractive index of air is n = 1.000002
