Which statement explains why increasing the
temperature increases the rate of a chemical
reaction, while other conditions remain the same?
(1) the reacting particles have less energy and
collide less frequently.
(2) the reacting particles have less energy and
collide more frequently.
(3) the reacting particles have more energy and
collide less frequently.
(4) the reacting particles have more energy and
collide more frequently.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
