the volume of the room is 240.588 meters3
The picture shows the scientific notation
Answer:
Yesssss its 1235 and you are beautiful
An electric engine turning a workshop sanding rotation at 1.00 × 10² rev/min is switched off. Take the wheel includes a regular negative angular acceleration of volume 2.00 rad/s². 5.25 moments long it takes the grinding rotation to control.
<h3>What is negative angular acceleration?</h3>
- A particle that has a negative angular velocity rotates counterclockwise.
- Negative angular acceleration () is a "push" that is hence counterclockwise.
- The body will speed up or slow down depending on whether and have the same sign (and eventually go in reverse).
- For instance, when an object rotating counterclockwise slows down, acceleration would be negative.
- If a rotating body's angular speed is seen to grow in a clockwise direction and decrease in a counterclockwise direction, it is given a negative sign.
- It is known that a change in the linear acceleration correlates to a change in the linear velocity.
Let t be the time taken to stop.
ω = 0 rad/s
Use the first equation of motion for rotational motion
ω = ωo + α t
0 = 10.5 - 2 x t
t = 5.25 second

Answer:

Explanation:
To solve this problem we need to apply the concept related to Angular Acceleration. We can find it through the equation

Where for definition,

The number of revolution
was given by 20 times, then


We know as well that the salad rotates 6 more times, therefore in angle measurements that is

The cook at the end stop to spin, then using our first equation,

re-arrange to solve
,


We can know find the required time,

Re-arrange to find t, and considering that 



Therefore take for the salad spinner to come to rest is 3 seconds with acceleration of 
What is the problem asking i would like to help but im kimd of confused
