Answer:
L = 239.2 J.s
Explanation:
The angular momentum of the rod is given by the following formula:
L = mvr
where,
L = Angular Momentum = ?
m = mass = 13.1 kg
r = radius of circle of rotation = length of rod = 2.15 m
v = linear speed of rod = r(angular speed of rod) = (2.15 m)(3.95 rad/s)
v = 8.5 m/s
Therefore,
L = (13.1 kg)(8.5 m/s)(2.15 m)
<u>L = 239.2 J.s</u>
B.) Elastic
Took the test and this is the answer
A second important difference between comets coming from the Kuiper Belt and from the Oort cloud is represented by their different characteristic periods.
In fact, short period comets are thought to generate in the Kuiper belt and have rather predictable orbits with short periods (up to 200 years). There are two major families of short period comets: the Jupiter family with periods of less than 20 years and the Halley family with periods form 20 to 200 years. That's short

Answer: The ball would exert and equal force on the astronaut in the opposite direction. Both would move away from each other in a straight path. Hope this helps!
