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>



The velocity is 4374.45 m/s.
I got the answer by using v=d/t.
20,000meters / 25min= 4,374.45 m/s.
The answer is <em>Compressional Stress
</em>
In geology, stress<span> is the force per unit area that is placed on a rock. ... This is called confining </span>stress<span>. Compression squeezes rocks together, </span>causing<span> rocks to fold or fracture (break). Compression is the most common </span>stress<span> at </span>convergent plate boundaries<span>.
I hope this helped!! Have a great day :D</span>
Answer:
925.04 J/s
Explanation:
T = 80 C = 80 + 273 = 353 K
To = 20 c = 20 + 273 = 293 K
A = 2 m^2
Use the formula for Stefan's law
Energy radiated per second


E = 925.04 J/s
