Answer:

longitudinal waves

Explanation:

Because they occur due to compressions and rarefactions.

Answer: Longitudinal Waves

Explanation: The particles of the medium pass parallel to the course that the heart beat moves. This sort of wave is a longitudinal wave. Longitudinal waves are usually characterised through particle motion being parallel to wave movement. A valid wave traveling thru air is a classic example of a longitudinal wave.

Why do planets orbit the sun (why don't they crash into the sun)?
Jobisdone [24]
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as we now understand Earth's gravity pulls down anything that isn't held up by some other force

What are factors within a region that affect or limit the physical environment?
NISA [10]

Answer:Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource.

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}

Consider a basketball player spinning a ball on the tip of a finger. If a player performs 1.99 J of work to set the ball spinnin
scoundrel [369]

To solve this problem it is necessary to apply the concepts related to rotational kinetic energy, the definition of the moment of inertia for a sphere and the obtaining of the radius through the circumference. Mathematically kinetic energy can be given as:

KE= I\omega^2

Where,

I = Moment of inertia

\omega = Angular velocity

According to the information given we have that the radius is

\Phi= 2\pi r

0.749m = 2\pi r

r = 0.1192m

With the radius obtained we can calculate the moment of inertia which is

I = \frac{2}{3}mr^2

I = \frac{2}{3}(0.624)(0.1192)^2

I = 5.91*10^{-3} kg \cdot m^2

Finally, from the energy equation and rearranging the expression to obtain the angular velocity we have to

\omega = \sqrt{\frac{2KE}{I}}

\omega = \sqrt{\frac{2(1.99)}{5.91*10^{-3}}}

\omega = 25.95rad/s

Therefore the angular speed will the ball rotate is 25.95rad/s
