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.

Matter is anything that has mass and takes up space. Substances are types of matter that are pure. Just remember that matter has mass and they both start with "m." Substances are <u>types of matter</u>. Cheers, mimiisawesome5
Answer: 70m
Explanation:
Given, 2 skaters, one with a mass of 60kg.
Another 75kg.
Distance is 14m.
Assuming the system centre if mass does not change, both skaters would meet at the centre of the mass
let the 60kg skater be xm away from the centre, then, the 75kg skater would be (14 - x)m away from the centre too
m1x + m2(14 - x) = 0
m1x + 14m2 - m2x = 0
60x + 14*75 - 75x = 0
60x - 75x + 1050 = 0
-15x + 1050 = 0
15x = 1050
x = 70
Thus, the distance the 65kg skater moves is 70m
