A sound wave has a speed of 345 m/s and a wavelength of 500 meters. Is it infrasonic, sonic, or ultrasonic

Physics

exis [7]2 years ago
4 0

Answer:

Infrasonic.

Explanation:

Given the following data;

Speed = 345 m/s

Wavelength = 500 meters

To find the frequency of the sound wave;

Speed = wavelength * frequency

Frequency = speed/wavelength

Frequency = 345/500

Frequency = 0.69 Hz

Therefore, the sound wave is infrasonic.

Note: Frequency of infrasonic sound = below 20 Hertz.

Frequency of sonic sound = 20 Hz to 20,000 Hertz.

Frequency of ultrasonic sound = above 20,000 Hertz.

What is the freezing point of radiator fluid that is 50% antifreeze by mass? k f for water is 1.86 ∘ c/m?
densk [106]
Ethylene glycol is termed as the primary ingredients in antifreeze.
The ethylene glycol molecular formula is C₂H₆O₂.
Molar mass of C₂H₆O₂ is = (2×12) +(6×1) + (216) = 62g/mol
Now that antifreeze by mass is 50%, then there is 1kg of ethylene glycol which is present in 1kg of water.
ΔTf = Kf×m
ΔTf = depression in the freezing point.
= freezing point of water freezing point of the solution
= O°c - Tf
= -Tf
Kf = depression in freezing constant of water = 1.86°C/m
M is the molarity of the solution.
=(mass/molar mass) mass of solvent in kg
=1000g/62 (g/mol) /1kg
=16.13m
If we plug the value we get 
-Tf = 1.86 × 16.13 = 30
Tf = -30°c

A person wants to determine the spring constant of an exercise stretch cord. He pulls the cord with a force probe that exerts a
Burka [1]

Answer:

350 N/m

Explanation:

If we are assuming the stretch does not exceed the elastic range of the material, then by Hooke's law the spring constant of the cord is simply the ratio between the force 70N acting on the cord to stretch 20cm or 0.2m

k = 70 / 0.2 = 350 N/m

The spring constant is 350 N/m

a baby carriage is sitting at the top of a hill that is 21 m high. the carriage with the baby has a mass of 1.5 kg. the carriage
Serga [27]
Height of baby carriage from ground = 21m

Mass of carriage with baby = 1.5 kg

The carriage has potential energy by virtue of its height.

Potential energy = mgh = 1.5×10×21 = 315 J

Hence, potential energy of the carriage is 315 Joule.

The main difference between a chest and a bounce pass is what?
snow_lady [41]

Answer: The main difference between the three is the mode of transmission. The chest pass is straight through the air towards your teammate. While the bounce pass is directed toward the ground and then at your teammate. Finally, the overhead pass is projected high in the air to avoid defenders.
