What component of a longitudinal sound wave is analogous to a trough of a transverse wave?

Physics
1 answer:
anzhelika [568]3 years ago
6 0

Explanation:

There are two components of a longitudinal sound wave which are compression and rarefaction. Similarly, there are two components of the transverse wave, the crest, and trough.

The crest of a wave is defined as the part that has a maximum value of displacement while the trough is defined as the part which corresponds to minimum displacement.

While compression is that space where the particles are close together while the rarefaction is that space where the particles are far apart from each other.

So, the refraction or the rarefied part of a longitudinal sound wave is analogous to a trough of a transverse wave.

A 1500-W electric heater is plugged into the outlet of a 120-V circuit that has a 20-A circuit breaker. You plug an electric hai
tekilochka [14]

Answer:

900 W.      

Explanation:

Given that

Electric heater 1500 W

We know that power P given as

P= V I

So the total power of 120 V and 20 A circuit

P = 120 x 20

P= 2400 W

So the power new load P'

P'= Total system power(P)- Electric heater load

P ' = 2400 - 1500

P'= 900 W

So the answer is 900 W.

Fiona claims that the diagram below shows simple machines, but Chad claims that it shows a compound machine.
Elza [17]

Answer:

Simple machine

Explanation:

It is a simple machine because the person wants to raise the load by an inclined plane. Simple machines perform work with the mechanical advantage offered by the machine itself, such as using a bar as Lever, lifting a load by means of a pulley. simple machines multiply or change direction a force. While Composite machines are the Union of several simple machines that perform a given job, examples of combined machines are found on bicycles, a washing machine, a car, and others.

A car accelerates along a straight road from rest to 90 km/h in 5.0 s. A) Find the magnitude of its average acceleration. B) Fin
egoroff_w [7]

Answer:

a)   A=5m/s^2

b)   V=25m/s

Explanation:

From the question we are told that:

Velocity v=90km/h=25m/s

Time t=5.0s

a)

Generally From Newton's motion equation for Average acceleration is   mathematically given by

  A=\frac{V-U}{t}

Since its from Rest Therefore

  U=0

 A=\frac{25m/s-0}{5s}

 A=5m/s^2

b)

Generally the equation for Average Velocity is mathematically given by

  V=u+at

 AT t=1.0s\\\\V=0+5(1)

 V=5m/s

 AT t=2.0s\\\\V=0+5(2)

 V=10m/s

 AT t=5.0s\\\\V=0+5(5)

 V=25m/s

1. Compare the speed that light waves travel in air to the speed that sound waves travel in the air. How many times faster do li
Vladimir79 [104]

Answer:

895522 times faster.

Explanation:

From the question given above, the following data were obtained:

Speed of sound in air (v) = 335 m/s

Speed of light in air (c) = 3×10⁸ m/s

How many times faster =.?

To obtain how many times faster light travels in air than sound, do the following

c : v => 3×10⁸ : 335

c/v = 3×10⁸ / 335

c/v = 895522

Cross multiply

c = 895522 × v

From the illustrations made above, we can see that the speed of the light in air (c) is 895522 times the speed of sound in air.

Thus, light travels 895522 times faster than sound in air.
