it is also known as formula for circumfrence which is 2 times pi times radius. if radius was 5 then the circumfrence would be 10pi.
Answer:
The astronaut will get a velocity 0.064ms−1 opposite to the direction of the object.
<span>The equation of motion for a rocket in
vertical flight can be obtained from newton’s second law of motion and is
constant-mass system. The equation of motion for a body mass varies with time and mass. When force acts on rocket, the rocket
will accelerate in the direction of force. Therefore, force is equal to the
change in momentum per change in time. For constant mass, force equals mass
times acceleration.</span>
Answer:
-67,500 kgm/s
Explanation:
1300 * 20 + 1100 * (-85) = -67,500 kgm/s
I believe it’s density and temperature
