Answer:
A pure substance in the gaseous state contains more energy than in the liquid state, which in turn contains more energy than in the solid state. Particles has the highest kinetic energy when they are in the gaseous state.

Explanation:
The number of sunspots, as you have learned, can indicate whether the sun is in a maximum-activity period or a minimum-activity period. Some scientists believe this can have an overall effect on the climate of Earth.
Explanation: There may be different explanations:
Suppose that Jane's car has a built some sped, and she sees a stoplight. Now she needs to stop the car (decelerating the car)
When she does this, she creates a force that holds the car until it is full stop, but this force is applied only on the car, the purse that is on the passenger seat only feels this force by the friction that the seat does in his surface, but the purse has built some moment because it was inside the car, and the friction force that the seat does may not be enough to also stop the purse. So when Jane stops, the purse keeps moving forward, and then it falls down of the seat.

Explanation:
Answer:
.35 s
Explanation:
x = v(i)t + 1/2at^2
gravity = 9.81 m/s^2 = a
.6 m = 1/2at^2
(.6 m) * 2 = (1/2at^2)*2
1.2 m = at^2
(1.2 m)/a = (at^2)/a
0.12 s^2 = t^2
sqrt(.12 s^2) = sqrt(t^2)
.35 s = t
