Answer:
small- even though they are huge suns themselves.
Explanation:
Sound waves are D) Mechanical and Longitudinal
Explanation:
In physics, waves are classified into two types:
- Mechanical waves are those waves that need a medium to propagate - these waves are produced by the vibrations of the particles of the medium
- Electromagnetic waves are produced by the alternating vibrations of electric and magnetic fields - they are the only waves that can also travel through a vacuum, so they do not need a medium
Moreover, waves are further classified into:
- Transverse waves are those in which the vibration of the wave occurs in a direction perpendicular to the direction of propagation of the wave
- Longitudinal waves are those in which the vibration of the wave is parallel (back and forth) to the direction of propagation of the wave
Sound waves are oscillations of a medium that occurs back-and forth along the direction of propagation of the wave. Therefore, they are mechanical (they need a medium to propagate) and longitudinal. So the correct answer is
D) Mechanical and Longitudinal

<u>Answer:</u> The temperature in degree Celsius is 301.31°C
<u>Explanation:</u>
To calculate the temperature, we use the equation given by ideal gas, which is:
P = pressure of the gas = 670 torr = 0.882 atm (Conversion factor: 1 atm = 760 torr)
V = volume of gas = 42.5 L
n = number of moles of gas = 0.795 mol
R = Gas constant = 
T = temperature of gas
Putting values in above equation, we get:
Converting the temperature from kelvins to degree Celsius, by using the conversion factor:
Hence, the temperature in degree Celsius is 301.31°C
