6. What is the freezing point of a solution of 0.5 mol of LiBr in 500 mL of water? (K = 1.86°C/m) O -1.86°C
-5.58°C
0 -3.72°C

the role of the microscope world in creating new materials .

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.
