A dentist’s drill starts from rest. After 4.28 s of constant angular acceleration it turns at a rate of 28940 rev/min. Find the

mylen [45]

Answer:

Angular acceleration, is $708.07\ rad/s^2$

Explanation:

Given that,

Initial speed of the drill, $\omega_i=0$

After 4.28 s of constant angular acceleration it turns at a rate of 28940 rev/min, final angular speed, $\omega_f=28940\ rev/min=3030.58\ rad/s$

We need to find the drill’s angular acceleration. It is given by the rate of change of angular velocity.

$\alpha =\dfrac{\omega_f}{t}\\\\\alpha =\dfrac{3030.58\ rad/s}{4.28\ s}\\\\\alpha =708.07\ rad/s^2$

So, the drill's angular acceleration is $708.07\ rad/s^2$ .

Sound must travel through a medium/body. Space is a vacuum so there is no medium/body for sound to travel through, so there is no sound.

Bumek [7]

Answer:

Yes, the car has acceleration.

Explanation:

Acceleration is defined as the rate of change of velocity. The velocity is a vector quantity. If a car is moving with constant speed but taking a turn, it means the velocity is changing, so the car have some acceleration.
