An atom of carbon with 6 protons, 6 neutrons, and 6 electrons would have an atomic mass of? (round to the nearest whole number)

The atomic mass would be 12.0107.

When rounding it to the nearest whole number, it would be 12

Explanation:

aka the element is Carbon.

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.
