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:

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

A neon lamp produces what kind of visible spectrum?

Shalnov [3]

Answer:

Discrete

Explanation:

There can be many kind of visible spectrum. Some of them are as follows :Infrared, Continuous , Blackbody and Discrete.

A neon lamp produces discrete kind of visible spectrum. In this type of spectrum, the spectrum consists of different colors. It means that the neon lamp is made up of different colors or individual frequencies.

Hence, a neon lamp produces discrete visible spectrum.

A toy cannon tosses a rubber ball straight upward. A motion sensor measures the speed of the ball as it leaves the cannon. Using

mezya [45]

Answer:

With this information is not possible to calculate the mass.

Explanation:

This is a characteristic problem of energy conservation, where kinetic energy becomes potential energy. For this particular problem, we have the initial speed as input data. The moment the ball comes out of the cannon we have the maximum kinetic energy, as the ball goes up the ball will gain more potential energy as the ball loses kinetic energy, until the moment the ball reaches the maximum height. At the maximum height point, the ball will have its maximum potential energy while its kinetic energy is zero. In other words, all the kinetic energy that was, in the beginning, was transformed into potential energy.
