Answer:
See below ~
Explanation:
The fact that water is attracted to itself, a property called <u>cohesion</u>, leads to another important property, the liquid form of water is <u>more</u> dense than the solid form. As water solidifies into ice, the molecules must move apart in order to fit in to a crystal lattice structure, causing water to expand as it freezes. Because of this, <u>ice floats</u> and water sinks, which keeps the oceans liquid and prevents them from freezing solid from the bottom up.

Answer:
The radius of the sphere is 4.05 m
Explanation:
Given;
potential at surface, = 450 V
potential at radial distance, = 150
radial distance, l = 8.1 m
Apply Coulomb's law of electrostatic force;
Therefore, the radius of the sphere is 4.05 m
