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
Thank you for posting your question here at brainly. Below is the solution:
Ke up top = 1/2*.25 *225
<span>gain of Pot energy = .25*9.81*1.2 </span>
<span>work input = (1/4)(2 pi *.6)*30 </span>
<span>so </span>
<span>sum of those 3 energies = </span>
<span>(1/2)(.25)v^2</span>
Ben was trying to <span>increase fluid friction. </span>

James Naismith was a physical education teacher
Sprinfield College
Upon the request of his boss, Naismith was tasked to create an indoor sports game to help athletes keep in shape as they endured the cold New England winters. Naismith's boss also stipulated that this new game should be "fair for all players and not too rough."
I just looked it up hope this helps tho.
Answer:c. labor-intensive.
Explanation:labor intensive is a process where a larger portion of total costs is due to labor as compared with the portion for costs incurred in purchase, maintenance, and depreciation of capital equipment. Example are Agriculture, construction, and coal-mining.
Industries that produce goods or services requiring a large amount of labor. Traditionally, labor intensive industries were determined by the amount of capital needed to produce the goods and services.
