The mass of 29000 N elevator is
Lana71 [14]

<span>In this case we are given a force of 29,000 N. We know that the equation we  can use is:</span>

Force = mass * acceleration

 

However this is not just any type of force, because this is the weight of the elevator. So when the force is equal to weight, the acceleration acting is simply gravity. Therefore:

 

weight = mass * gravity

 

Calculating for mass:

mass = 29,000 N / (9.8 m/s^2)

<span>mass = 2,959.18 kg</span>

The trough of the sine curve used to represent a sound wave corresponds to
iren [92.7K]

Answer:

The correct answer is a rarefaction.

Explanation:

Sound waves are longitudinal waves that propagate in a medium, such as air. As the vibration continues, a series of successive condensations and rarefactions form and propagate from it. The pattern created in the air is something like a sinusoidal curve to represent a sound wave.

There are peaks in the sine wave at the points where the sound wave has condensations and valleys where it has rarefactions.

Have a nice day!
