Answer:

Explanation:
Given:
- moment of inertia of the skater with extended arms,

- moment of inertia of the the skater with pulled-in arms,

- angular velocity of the skater with extended arms,

<u>Using the law of conservation of angular momentum:</u>



Answer:
Explanation:
The formula for kinetic energy Ke=1/2mv^2 where Ke is kinetic energy, m=mass, and v= velocity.
If the kinetic energy is increased that means that there must be an increase in mass or velocity. However, since the velocity is squared that means that velocity affects the kinetic energy of the object more than the mass does.
Answer: Blake may have a decreased chance of disease.
Explanation:
Research has shown that on average, a person who engages in more physical activity will live longer than a person who does not with one reason for this being that engaging in physical activity helps reduce the risk of diseases such as; heart disease, diabetes, and many forms of cancer.
Obesity (risk factor) and high blood pressure are also reduced by engaging in physical activity.
It depends on the environment around you ... the number and size of
the masses around you, and your distance from their center of mass.
If you happen to be on the surface of the Earth, then
g = 9.8 m/s²
or
g = 9.8 newton/kilogram .
It's different on other planets. Be sure to look it up
before you leave, so you'll know what to expect.
