Calculate the average velocity of the cart for each fan speed. Round your answers to the nearest tenth.
serg [7]
<h2>Answer:</h2>

Answers in the explanation

<h2>Explanation:</h2>

The term speed is used to denote distance  traveled divided by time. This can be expressed in a mathematical language as follows:

v=\frac{d}{t} \\ \\ \\ v:speed \\ \\ d:distance \\ \\ t:time

The cart with Low fan speed:

v=\frac{500}{7.4} \\ \\ v=67.5675cm/s \\ \\ Rounding \ to \ the \ nearest \ tenth: \\ \\ \boxed{v=67.6cm/s}

The cart with Medium fan speed:

v=\frac{500}{6.4} \\ \\ v=78.125cm/s \\ \\ Rounding \ to \ the \ nearest \ tenth: \\ \\ \boxed{v=78.1cm/s}

The cart with High fan speed:

v=\frac{500}{5.5} \\ \\ v=90.9090cm/s \\ \\ Rounding \ to \ the \ nearest \ tenth: \\ \\ \boxed{v=90.9cm/s}

Sound waves are a- Transverse b- Longitudinal c- Transverse and longitudinal
Katen [24]

Answer:

Sound waves are longitudinal in nature.

Explanation:

There are many types of waves like transverse, longitudinal, electromagnetic wave etc.

Sound waves are longitudinal in nature. In longitudinal type of wave, the medium particles moves parallel to the propagation of the wave. This type of waves move in the form of compression and rarefaction.

In compression, the particle density at a point is very less while in rarefaction, the particle density at a point is very high.

So, the correct option is (b) "longitudinal wave".
