Answer:
The correct option is;
C. The temperature of the air affects the speed of sound
Explanation:
The information given are;
The speed with which sound travels in the desert air = 358 m/s
The speed with which sound travels in the polar air = 330 m/s
The major difference between the desert air and the polar air is that the temperature of the desert air is hotter than the temperature of the air in the polar region. Therefore the speed of sound is affected by the air temperature.
The equation that gives the relationship of the speed of sound in air, 
, to temperature is presented as follows;
Which shows that the speed of sound in air, , rises as the temperature of the air rises.
Where;
= The temperature of the air in degrees Celsius
= The temperature of the air in degrees Kelvin.
A would be the best answer beacuse
Ovaries - small, oval-shaped glands that are located on either side of the uterus. The ovaries produce eggs (ova - an ovum is one egg, ova means multiple eggs.) The ovaries also produce the main female sex hormones which are released into the bloodstream.
Mohs scale of mineral hardness is a qualitative scale that characterizes the scratch resistance of various minerals with the ablity of harder material to scratch softer material
Answer:
is the density of the oil
Explanation:
Given:
- height of oil column,
- oil column height that is more than the water column height in the other arm,
<u>Now from the given it is clear that the height of water column is:</u>
Now according to the pressure balance condition of fluid columns:
Pressure due to water column = Pressure due to oil column
is the density of the oil
