The radius of the new moons orbit is R= 7.715 x 10^7 m
The orbital period of the moon is T= 14.48 hr
Answer:

Explanation:
Given that:
Height of jump, 
length of elastic cord, 
spring constant of the cord, 
mass of the body that jumps, 
Force on the bungee elastic cord:


Now this force F will be responsible for the elongation in the elastic cord, so:
............................(1)
where :
k = spring constant
x = extension in the elastic cord
using eq. (1)


So the cord stretches 19.6 meters more beyond its original length of 30 meters.
Hence, the remaining distance from the river surface at the bottom is:


A statement which describes the changes that occur in this sequence of events is: 2. matter is converted into energy and then energy is converted into matter.
<h3>What is the law of conservation of matter?</h3>
The law of conservation of matter (LOCOM) states that mass can neither be created nor destroyed in any chemical reaction.
Similarly, the energy possessed by a matter can neither be created nor destroyed, but it can only be converted from one energy form to another.
In this context, we can logically deduce that a statement which best describes the changes that occur in this sequence of events is that matter is converted into energy and subsequently, energy is converted into matter.

Density is mass divided by volume. rho=m/v. So, v=m/rho. In frank's case this is 80/8 = 10 cm^3.
