A trombone has a variable length. When a musician blows into the mouthpiece and causes air in the tube of the horn to vibrate, the waves set up by the vibrations reflect back and forth in the horn to create standing waves. As the length of horn is made shorter, what happens to the frequency?A) The frequency will increase or decrease depending on how hard the horn player blows.
B) The frequency will increase
C) The frequency will decrease
D) The frequency will increase or decrease depending on the diameter of the horn.
E) The frequency will remain same

Answers

Answer 1

Answer:

Answer:

B) The frequency will increase

Explanation:

The length of the instrument is given by

$L=(\lambda)/(2)\n\Rightarrow \lambda=2L$

Wavelength is given by

$\lambda=(v)/(f)$

$(v)/(f)=2L\ or\ L\propto (1)/(f)$

It can be seen that the length is inversely proportional to the frequency.

Here, the length of the trombone is decreasing so the frequency will increase.

What can cause a big city to be warmer than the surrounding countryside?

Answers

In cities, a phenomenon known as the "urban heat island effect" causes air temperatures to be warmer than in nearby suburban or rural areas and

Area with lower atmospheric pressure than its surrounding areas; this makes air from surrounding areas to flow into the low, the end result of which is probably cloudiness and precipitation.

Answers

Answer:

"Low pressure system"

Explanation:

The area you are describing is known as a "low-pressure system" in meteorology. In a low-pressure system, the atmospheric pressure at the surface is lower than the pressure in the surrounding areas. This difference in pressure causes air from the surrounding areas to flow into the low-pressure region, creating a circulation pattern. As the air rises within the low-pressure system, it cools and can lead to the formation of clouds and precipitation. Low-pressure systems are often associated with stormy weather and can bring rain, snow, or other forms of precipitation, depending on the temperature and moisture content of the air.
