Answer:

The angular acceleration of CD player is 13.93\ rad/s^2.

Explanation:

Initial angular speed of a CD player is 0 and final angular speed is 41.8 rad/s. Time to change the angular speed is 3 s.

It is required to find the angular acceleration. The change in angular speed of the CD player divided by time taken is called its angular acceleration. It can be given by :

a=\dfrac{\omega_f-\omega_i}{t}\\\\a=\dfrac{41.8-0}{3}\\\\a=13.94\ rad/s^2

So, the angular acceleration of CD player is 13.93\ rad/s^2.

The zero tolerance law applies to drivers _________.
s2008m [1.1K]

The zero tolerance law applies to drivers <u>under the age of 21.</u>

<h3>Zero Tolerance Law:</h3>

Drivers under the age of 21 who operate a motor vehicle with a BAC of between 0.02% and 0.07% are subject to what is known as the "Zero Tolerance Law." The Zero Tolerance Law aims to prevent underage drivers from driving after consuming alcohol.

The zero-tolerance rule states that it is against the law for anyone under the age of 21 to operate a motor vehicle while having any detectable level of alcohol in their system. Zero Tolerance Law states that a minor has committed the criminal offense of DUI if there is ANY detectable level of alcohol in his or her system while operating a vehicle in public. The minor's driver's license is immediately suspended, and the officer has the authority to confiscate the license on the spot.

The voltage across the secondary winding is 10,000 V, and the voltage across the primary winding is 25,000 V. If the primary win
Allisa [31]

<u>Answer</u>

80 coils


<u>Explanation</u>

The turn rule of a transformer says that, the amount of voltage induced in the secondary coil is proportional to the number of coil. It is simplified by the ratio:

N<em>p/</em><em>N</em><em>s  =  </em><em>V</em><em>p/</em><em>V</em><em>s</em>

200/Ns  = 25,000/10,000

200 × 10,000  = 25,000Ns

2,000,000 = 25000Ns

Dividing both sides by 25,000,

Ns = 2,000,000/25,000

       = 80 coils

The first law of thermodynamics states the conservation of energy and heat where the total energy in an isolated system may be transformed into another, but never created or destroyed. If 286 J of energy was released to the room, then also 286 J of energy was also removed from food in that refrigerator assuming it is an isolated system.   :)

A roller coaster car of mass m= 300 kg is released from rest at the top of a 60 m high hill (position A), and rolls with a negli
Andrews [41]

Answer: The principle of conservation of energy, angular speed and centripetal force

Explanation:

At point A, the car experienced maximum of potential energy

As it moves down the hill, the potential energy decreases while the kinetic energy increases.

The maximum kinetic energy of the car is needed for the attainment of enough centripetal force to help the car move through the loop without falling .
