Correct answer: B
The force of gravity acting on the object on the moon can be found by multiplying its mass by the acceleration due to gravity on the moon. The acceleration due to gravity on the moon is a constant and is approximately 1.63m/s².
120kg×1.63m/s²=195.6kg.m/s²
kg.m/s²=N
<span>The force of gravity acting on the object on the moon would be of approximately 196N.</span>
yes
evaporation starts on the surface
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.

Answer:
Pure research is conducted without any specific goal in mind. Applied research is conducted in order to solve a specific and practical problem, unlike pure research. Hope this helped.
Answer:
a) The force is zero, or the displacement is zero, or the angle is 180 degrees
b) The kinetic energy, speed, and velocity of the particle change.
