Explain how wood produces chemical energy? A. Gases such as carbon dioxide and oxygen react to produce chemical energy.

B. Chemical energy is found naturally in wood.

C. Wood is living organism that absorbs sunlight to make chemical energy.

D. Cells in the wood naturally make chemical energy

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 electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

i do not get it   at all

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
