5. after a day of testing race cars, you decide to
take your own 1550-kg car onto the test track.
while moving down the track at 10 m/s, you

Describe the interaction that occurs between two objects with the same electrical charge.

You exhale co2 which is produced during cellular respiration.  co2 combines with the water in your blood's plasma to make up one half of the body's most important buffer pair, carbonic acid.  the more physical activity you engage in, the more co2 your body is producing.  you can see this by putting some of the cabbage indicator in a glass and then blowing bubbles into it through a straw.  can you see a change in the color of the indicator?
