Answer:
The change in angular momentum is 
Explanation:
From the question we are told that
The initial angular velocity of the spinning top is 
The angular velocity after it slow down is 
The time for it to slow down is 
The rotational inertia due to friction is 
Generally the change in the angular momentum is mathematically represented as

substituting values


Answer:
According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up.

I’m pretty sure it’s hertz
but if it’s wrong i apologize
Answer:
is that a really questions
Psychologists study animals because they want to understand how different species think and behave, animal psychology is often simpler and easier to understand than human physiology, and it is more permissible to conduct certain types of research with animals than with humans
