Which of the following statements is true? plasma can be found in lightning and comet tails. liquid molecules also have a strong attraction to one another. bose-einstein condensates form at absolute zero. all of the above.

All of the above.

Explanation:

Liquid molecules are very attracted to eachother, and to the surface of the containers that holds them, the Bose Eisntenin condensates form at near absolute zero, and plasma can be found in lightning and comet tails, and since everyone is truth, all of the above is the correct option.

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.
