Question 7 (01.03 LC)
Which of the following happens to a molecule of an object when the object is cooled?
a) Its temperature increases,

b) It loses kinetic energy.

c) Its size increases.

d) It moves faster.

Particles vibrate in a rigid structure and do not move relative to their neighbors.

In a copper wire, a temperature increase is the result of which of the following

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
