3. The following sound waves have what velocity? (convert cm into m in your calculations.)

1 answer:

6 0

The sound waves with the frequency 20 Hz, 200 Hz, 2,000 Hz, and 20,000 Hz have a velocity of 344 m/s.

<h3>What are sound waves?</h3>

A sound wave is a sample resulting from the motion of strength traveling thru a medium (inclusive of air, water, or every other liquid or stable matter) because it propagates from the supply of the sound. Sound waves are created and convey strain waves, for example, a cellphone.

The frequency can be given as:

Frequency = Velocity/ Wavelength

Velocity = Frequency * Wavelength

The velocity of the following sound waves is given as:

Frequency = 20 Hz

Wavelength = 17.2 m

Velocity = 20 * 17.2 m/s

Velocity = 344 m/s

Frequency = 200 Hz

Wavelength = 1.72 m

Velocity = 200 * 1.72 m

Velocity = 344 m/s

Frequency = 2,000 Hz

Wavelength = 17.2 cm = 0.172 m

Velocity = 2,000 * 0.172 m/s

Velocity = 344 m/s

Frequency = 20,000 Hz

Wavelength = 1.72 cm = 0.0172 m

Velocity = 20,000 * 0.0172 m/s

Velocity = 344 m/s

the electric field midway between two equal but opposite point charges is 573 n/c , and the distance between the charges is 16.0

saveliy_v [14]

The electric potential between the two charges is 91.68 V.

<h3>Electric potential between the two charges</h3>

The electric potential between the two charges is calculated as follows;

V = Ed

where;

V is electric potential
E is electric field
d is the distance of the charge

Substitute the given parameters and solve for electric potential,

V = 573 N/c x 0.16 m

V = 91.68 V

Thus, the electric potential between the two charges is 91.68 V.

A motorcycle is capable of accelerating at 5.1 m/s starting feom rest how far can it travel im 1.5 seconds

saul85 [17]

5.1 m/ s

~Multiply 1.5 on both sides since you’re trying to finding out how far it can travel in 1.5 seconds

5.1 x 1.5= 7.65

s x 1.5= 1.5

So a motorcycle can travel 7.65 m in 1.5 seconds.

In a sublimation apparatus, the water pressure in the connected aspirator should be ________. A water pressure that is too low w

Alika [10]

Answer:

A) The water should be well sealed by putting a water trap between the aspirator and the sublimator to avoid water backing up and filling the sublimator as a result of sudden pressure drop.

B) Variation in water pressure could cause water to back up and fill the sublimator.

<h3>What is simple pendulum?</h3>

A simple pendulum can be defined as the equipment that displays an oscillatory motion when a mass is tied on a rope and is suspended from it.

The various movements that occur using a simple pendulum is translational ( side to side) or continuous circle (oscillatory motion).

The equation that show that a change from one type of motion to another is H = 2g/l.
