Answer:
The magnitude of angular acceleration is 
.
Explanation:
Given that,
Initial angular velocity, 
When it switched off, it comes o rest, 
Number of revolution, 
We need to find the magnitude of angular acceleration. It can be calculated using third equation of rotational kinematics as :
So, the magnitude of angular acceleration is . Hence, this is the required solution.
Answer:
9.51
Explanation:
The distance s is given by:
The change in distance is given by the time derivative of s:
For the time t you solve the equation of distance x for time:
Plugging in for t:
Barometer duhhhh what’s else a ruler
Answer:
The center of the Milky Way most likely contains a supermassive black hole.
Explanation:
Because it is an eleptical galaxy, it has a little rotation to it but not enough to flatten out so the center will contain a supermassive black hole.
