Answer:
"0.049 W" is the correct answer.
Explanation:
According to the given question,



As we know,
⇒ 


Now,
⇒ 



or,

Answer:
An increase in angular speed due to conservation of energy priciple.
Explanation:
This leads to a decrease in your moment of inertia. This means that your angular velocity must increase as a result of conservation of energy principle and therefore you will spin faster.
It's also the same way this conservation of energy principle applies to ice skaters that makes them spin faster when they suddenly draw their arms inwards.
Answer:
Price=$7×10⁷
Explanation:
Step 1: Estimate the volume of the pile,
Step 2: Multiply it by the density to get its mass
Step 2: Then multiply the mass by the price per gram to get the total price
So
The average pile dimensions are=45.7×45×172.7

Price=m×$10
Price=(7×10⁶)×$10
Price=$7×10⁷
