Ans: Thus, the kinetic energy change = 4.5 JThe mass of puppy = 3kg
Kinetic energy initial =
=
Kinetic energy final =
Thus, the kinetic energy change = 4.5 J
he makes 1 m im 300 seconds btw that snails slow lol
When jumping on a trampoline, the energy changes from potential to kinetic energy constantly. when you begin to jump in the air there is kinetic energy present, and when you reach maximum height then potential energy takes over for a little bit. Then, when going back down, kinetic energy takes over again until you land on the trampoline.
Hope this helps,

Answer:
<u>Jupiter and Saturn</u>
Explanation:
Giant planets -
Giants planets have maximum moons ,
for example ,
Jupiter and Saturn .
Jupiter have 63 moons ( according to 2009 calculation ) , where , 8 moons are the regular satellites , 4 moons are spherical and large , 4 moons are small and close to Jupiter , in addition to it Jupiter have 55 irregular satellites .
Second highest moon is with planet Saturn , with 61 moons .
Many of moon's are thought to have been captured from the small-body population during the formation of the solar system .
Answer:
(a) ![[Y_{p} ]_{max} = \frac{2f}{1+f}](https://tex.z-dn.net/?f=%5BY_%7Bp%7D%20%5D_%7Bmax%7D%20%3D%20%5Cfrac%7B2f%7D%7B1%2Bf%7D)
(b) 
; ![[Y_{p} ]_{max}](https://tex.z-dn.net/?f=%5BY_%7Bp%7D%20%5D_%7Bmax%7D%20)
= 0.026
Explanation:
Since the neutron-to-proton ratio at the time of nucleosynthesis is given:
Therefore:
Then, to determine the maximum ⁴He fraction if all the available 
neutrons bind to all the protons. Since, there are 2 protons and 2 neutrons in a ⁴He nucleus, it shows that there would be 
nuclei of ⁴He.
In addition, a ⁴He nucleus has a mass of 
, where 
is the mass of one proton. Thus, nuclei of such nuclei will have a mass of *.
Assuming that 
, there would be a total of 
protons and neutrons with a total mass of 
.
Thus:
(b) Given:
; τ
= 3*60s = 180 s
![f_{new} = \frac{n_{nf} }{n_{pf} } = \frac{exp (-200/180)}{5 +[1- exp(-200/180)]} =\frac{0.077}{5.923} = 0.013](https://tex.z-dn.net/?f=f_%7Bnew%7D%20%3D%20%5Cfrac%7Bn_%7Bnf%7D%20%7D%7Bn_%7Bpf%7D%20%7D%20%3D%20%5Cfrac%7Bexp%20%28-200%2F180%29%7D%7B5%20%2B%5B1-%20exp%28-200%2F180%29%5D%7D%20%3D%5Cfrac%7B0.077%7D%7B5.923%7D%20%3D%200.013)
= (2*0.013)/(1+0.013) = 0.026
