Speed = distance/time taken
1484 = distance/3
Distance = 1484 x 3
Distance = 4452 m
Answer:

Explanation:
As we know that the relation between temperature and pressure is a linear relation
so we have

here we know that




now we will have


now if P = 0
then we will have


Answer:
Option D is your answer ☺️☺️. If I'm right so,
Please mark me as brainliest. thanks!!!
First of all we need to convert everything into SI units.
Let's start with the initial angular speed,

. Keeping in mind that


we have

And we should also convert the angle covered by the centrifuge:

This is the angle covered by the centrifuge before it stops, so its final angular speed is

.
To solve the problem we can use the equivalent of

of an uniformly accelerated motion but for a rotational motion. It will be

And by substituting the numbers, we can find the value of

, the angular acceleration:
