Which of the following statements are true of gases?

check all that apply.

a. the particles have more kinetic energy than those of liquids or solids.
b. they have strong intermolecular forces between the atoms or molecules.
c. the particles are in a fixed location.
d. the particles can move anywhere.

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.

m=9
