Answer:
B
Explanation:
Mass is the amount of matter in an object. Weight is the force of gravity on an object.
b. Float
Explanation:
A liquid with a specific gravity of less than one with combined with water will definitely float upon it.
Specific gravity is also known as relative density. It is the density of a substance compared to the density of water.
When a substance has higher density than water it will sink in it.
A substance with a density lower than that of water will float and stay on top of it.

The pull of the moon on Earth's tidal bulge is causing The moon to slowly move farther away from the Earth. Hope that helps.
Solution :
a). From Newtons second law,
F = ma
The total tension force is 2T.
∴ 2T - (m + M)g = (m+ M)a
Then
b). From the person,
F = ma
T - Mg + N = Ma
or N = Ma + Mg - T
= (63 x 9.8) + (52 x 9.8) - 600
= 617.4 + 509.6 - 600
= 527 N
