An optical disk drive in a computer can spin a disk at up to 10,000 rpm. If a particular disk is spun at 7570 rpm while it is be
anastassius [24]

Answer:

The magnitude of the average angular acceleration is calculated as 1822.36\ rad/s^{2}

Explanation:

Maximum speed that can be attained by the disk, N_{m} = 10,000 rpm

Speed of spinning of the disk, N = 7570 rpm

Time taken to come to rest, t = 0.435 s

Now,

The initial angular velocity is given by:

\omega = \frac{2\pi N}{60} = 792.73\ rads^{-1}

Final angular velocity, \omega' = 0\ rads^{- 1}

The average angular acceleration of the disk can be computed by using the kinematic eqn:

\omega' = \omega + \alpha t

0 = 792.73 + 0.435\alpha

\alpha = - 1822.36\ rads^{- 2}

How does work affect energy between objects so it can cause a change in the form of energy?
mihalych1998 [28]

Answer:

Doing work' is a way of transferring energy from one object to another, energy is transferred when a force moves through a distance.

Explanation:  So more energy, more work done bc u transferred more energy to move the object and doing the work. and if you only use a little of energy, the work done also only a little.

An object with a mass of 2.0 kg accelerates 2.0 m/s 2when an unknown force is applied to it. What is the amount of force?
Musya8 [376]

Answer:

4 N

Explanation:

mass = 2 kg

acceleration = 2 m/s^2

Force = mass * acceleration

         = 2 *2

         = 4 N

I need it now aaaasssssaaaappp!!!!
Vera_Pavlovna [14]

A) Pitch depends on the frequency of a sound wave. The higher the pitch, the higher the frequency and the lower the pitch, the lower the frequency. Sound waves have different pitches due to varying frequency levels.

B) Sound is created as the pen vibrates. This vibrations also interacts with the air atoms and molecules, causing them to vibrate too, therefore, creating sound waves. The reason the brain grows annoyed at this continual sound is because the brain will focus on this sound only, causing the brain to go into overdrive, creating annoyance.

C) Sound waves are travelling vibrations of particles. Space does not have any atoms or particles for the sound vibrations to interact with, therefore creating zero sound waves to travel.

Hope this helps!! :))
