Two musicians are comparing their trombones. The first produces a tone that is known to be 438 Hz. When the two trombones play together they produce 6 beats every 2 seconds. Which statement is true about the second trombone? It is producing a 444-Hz sound, and could be producing no other sound frequency. It is producing either a 436-Hz sound or a 440-Hz sound. It is producing either a 435-Hz sound or a 441-Hz sound. It is producing either a 432-Hz sound or a 444-Hz sound. It is producing a 441-Hz sound, and could be producing no other sound frequency.
Answers
Answer:
It is producing either a 435-Hz sound or a 441-Hz sound.
Explanation:
When two sound of slightly different frequencies interfere constructively with each other, the resultant wave has a frequency (called beat frequency) which is equal to the absolute value of the difference between the individual frequencies:
(1)
In this problem, we know that:
- The frequency of the first trombone is
- 6 beats are heard every 2 seconds, so the beat frequency is
If we insert this data into eq.(1), we have two possible solutions for the frequency of the second trombone:

What happens during a muscle contraction?
During a muscle contraction, the sliding of the filaments pulls the Z discs of a sarcomere closer together, then shortens the sarcomere. This is when muscle contraction happens!

Answer:
45.6°C
Explanation:
Kinetic energy =
Use m= 1.80kg and v=7.80m/s (mass and speed of hammer).
K = 0,5*1.80kg*(7.80m/s)^2 = K=54.8J
Heat is 60% of Kinetic energy. Q = 0.6*54.8J = 32.9J
As it is stuck 10 times the total heat is 10*32.9J = Total Heat = 329J
Use the equation to find change of temperature:
Q = 329J; m = 8.00g of aluminium; C_v = 0.900J/g°C (For aluminium)
Calculating gives Change of Temperature = 45.6°C

Sound waves travel fastest through the ground.
What is meant by a longitudinal wave ?
A longitudinal wave is a form of wave in which the medium vibrates parallel to the direction of the wave.
Here,
The displacement of the medium moves with the wave motion in the same direction.
Sound waves are longitudinal waves because, the direction of the energy transport is parallel to the oscillations of the sound waves.
Since, it is created by compressions and rarefactions in the air, sound waves are known as longitudinal waves. The air particles vibrate in a direction that is parallel to the direction of propagation.
The sound waves require a medium to propagate.
Solids and liquids have the quickest sound wave propagation rates, whereas gases have the slowest. Gases are very loosely packed while liquids are not as securely packed as solids. Sound moves through solids much more quickly than it does through gases due to the distance between the molecules.
Hence,
Sound waves travel fastest through the ground.

Answer: The correct option is the ground.
Explanation:
Sound is a longitudinal wave. In longitudinal wave, the particles vibrate parallel to the direction of the propagation of the wave.
It needs medium to travel. It can travel in solid, liquid and gas.
Sound wave travels faster in solid in comparison to liquid.
It travels slowest in air.
Ground is a denser medium. Here, the sound wave travels faster in comparison to the ocean and the air.
Therefore, the correct answer is the ground.

Explanation:
When a single wavelength wave which is known as a monochromatic light is passed from one transparent medium to the other, it can refract. This refraction can only be seen if the light enter the medium at some angle.
