Answer: The weight of the astronaut on earth is greater than his weight on the moon.
Explanation:
The reason I got this answer is because the astronaut will have the same mass on the moon as he does on earth. Also the weight of a person or object is determined by gravity. So since the moons gravity isn’t as strong as earths gravity the astronauts are lighter in terms of weight, and this is how they slightly float.
Answer:
The automobile tire rotates 91 revolutions
Explanation:
Given;
angular acceleration of the automobile, α = 2.13 rad/s²
time interval, t = 23.2-s
To calculate the number of revolutions, we apply the first kinematic equation;

the initial angular velocity is zero,

Find how many revolutions that are in 573.2256 Rad

Therefore, the automobile tire rotates 91 revolutions
The lowest point, where the amount of energy is the greatest
