a small sample of gas has initial pressure 4.45 atm at 285 K. It warms up and the pressure decreases, so that the final pressure is o.97 atm at 297 K. At that time the gas sample is 30.7 ml. What is the initial volume of the gas sample? (th is an ideal gas

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 answer would be a
