The major difference is: Mercury has no orbiting satellites, while Jupiter has many satellites that surround it, so the correct answer is C
Matter is radioactive and decays over time

Answer:
a) 42.9 m/s
b) 41.6m
Explanation:
a) ![V_{0x}=V_{0y}=\frac{v}{\sqrt{2} }](https://tex.z-dn.net/?f=V_%7B0x%7D%3DV_%7B0y%7D%3D%5Cfrac%7Bv%7D%7B%5Csqrt%7B2%7D%20%7D)
![y(t)=0.3+\frac{v}{\sqrt{2} }t -4.9t^{2} \\188=\frac{vt}{\sqrt{2}} \\](https://tex.z-dn.net/?f=y%28t%29%3D0.3%2B%5Cfrac%7Bv%7D%7B%5Csqrt%7B2%7D%20%7Dt%20-4.9t%5E%7B2%7D%20%5C%5C188%3D%5Cfrac%7Bvt%7D%7B%5Csqrt%7B2%7D%7D%20%5C%5C)
solving the eq we get
v=42.9 m/s
b) <em>here,</em>
![t=\frac{116\sqrt{2} }{42.9}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B116%5Csqrt%7B2%7D%20%7D%7B42.9%7D)
when put in y(t) it gives y=44.6 m so result is
h=44.6-3= 41.6m
