ANY closed orbit exists because of the centripetal force of gravity.
Without the force of gravity, the satellite would simply sail away
in a straight line.
The orbit you're describing happens to be a circular orbit, but it
doesn't have to be circular.
So for an incident rag from vacuum to a medium with n=1.6, and an incident angle of 53 degrees, the the angle of refraction will be .
P= mv
where p is momentum
m is mass
v is velocity
so it's given p= 100kgm/sec
v= 4m/s
so putting in the formula
100= m × 4
m = 25kg
C. Physicalist chemist and biologist conducted experience in gather collection that changed existing scientific knowledge about the oceans
Explanation:
The voyage of Her Majesty's Ship was highly important because it furnished scientists with rich evidence about a lot of phenomenon under study and this changed existing scientific knowledge about the ocean.
- H.M.S II was an expedition to study and map the ocean floor using some sophisticated and newer devices.
- It was through this expedition that the theory of plate tectonics was modified and became a theory
- The bathymetry of the ocean floor was also carried out.
- The mid-oceanic ridge was discovered through the expedition.
- Some rare species of organisms were also obtained from the ocean floor in this process.
- The H.M.S second expedition after the world war was very crucial and helped furthered scientific knowledge about the oceans.

<span>The atomic number of
a neutral atom is equal to the number of protons and the number of electrons of
the atom. The atomic weight meanwhile is equal to the sum of the number of
protons and number of neutrons. In this case, the number of protons is equal to 26. The number of neutrons hence is 30. </span>
