Answer:
(A) more rapidly than
Explanation:
With higher temperatures, object's molecules (and atoms) have higher kinetic energy which is due to faster "jiggling" (vibrations). On a hot day these vibrations in the material the sidewalk is made of are more rapid than on a cold day, just as their temperatures differ.
Ionic compounds are made up of two charged species, a cation (+) and an anion (–).
The charges must balance out to zero for a stable ionic compound, because ionic bonds are formed between two charged species. They form in ratios according to their charges to balance out.
Infra-red has wavelengths just longer than visible light.

Torque = r x F
|F| = mg = 60 * 10 N = 600 N ( assuming g ~ 10m/s^2)
distance of fulcrum = torque / Force = 90/600 m = .15 m.
