A spinning wheel on a fireworks display is initially rotating in a counterclockwise direction. The wheel has an angular accelera

nalin [4]

Answer:

5.74s

Explanation:

We can first solve for the initial angular velocity using the following formula

$\omega^2 - \omega_0^2 = 2\alpha\theta$

Where $\omega = -22.4rad/s$ is the final angular velocity, $\alpha = -22.4 rad/s^2$ is the angular acceleration and $\theta = 0$ is the angular displacement

$22.4^2 - \omega_0^2 = 2*(-7.8)*0$

$\omega_0^2 = 22.4^2$

$\omega_0 = 22.4rad/s$

So for the wheel to get from 22.4 to -22.4 with angular acceleration of -7.8 then the time it takes must be

$t = \frac{\Delta \omega}{\alpha} = \frac{-22.4 - 22.4}{-7.8} = 5.74s$

Explain why gases are good insulators?

Zepler [3.9K]

Answer:Gases do not conduct heat as well as liquids and are therefore good insulators. Gases consist of widely spread out particles, and it takes contact to conduct heat. ... They are insulators if they are not ionized and there are no free charged particles there that can carry electric current.

Light has a frequency of about 6 x1014 Hz.

abruzzese [7]

Answer:

The visible light frequency is 400 THz to 700 THz, approximately. A THz is a Terahertz, which is a unit of frequency equal to one trillion Hertz.

What is the SI unit of force?

seraphim [82]

The SI unit of force is the<em> Newton</em> .

1 Newton is the force that accelerates 1 kilogram of mass at the rate of 1 meter per second-squared.

1 pound of force is roughly 4.45 Newtons of force.

So 1 Newton of force is roughly 3.6 ounces of force.

1 kilogram of mass weighs about 9.81 Newtons on Earth. That's the same as 2.205 pounds.
