Which are examples of a medium? water and air amplitude and wavelength crests and troughs compressions and rarefactions

umka21 [38]

Answer:

water and air

Explanation:

A wave is a transmission of a disturbance from one point or the source to another point.
Transmission of a wave occurs through a material medium or a vacuum. Therefore a medium is the material through which a wave travels through.
The medium may be in gaseous form, slid form or liquid form. Therefore water and air are example of medium of transmission of a wave.

A gas in a sealed container has a pressure of 50 kPa at 27°C. What will the pressure of the gas be if the temperature rises to 8

alexgriva [62]

Answer:

the final pressure of the gas is 60 kPa.

Explanation:

Given;

initial pressure of the gas, P₁ = 50 kPa = 50,000 Pa

initial temperature of the gas, T₁ = 27⁰ C = 27 + 273 = 300 k

final temperature of the gas, T₂ = 87⁰ C = 87 + 273 = 360 K

Let the final pressure of the gas = P₂

Apply pressure law;

$\frac{P_1}{T_1} = \frac{P_2}{T_2} \\\\P_2 = \frac{P_1T_2}{T_1} = \frac{50,000 \times 360}{300} = 60,000 \ Pa = 60 \ kPa$

Therefore, the final pressure of the gas is 60 kPa.
