I figured it out nvm !! Read through the scenarios below and calculate the predicted change in kinetic energy of the object compared to a 50 kg ball traveling at 10 m/s A 50 kg ball traveling at 20 m/s would have kinetic energy.

A 50kg ball traveling at 5 m/s would have kinetic energy.

A 50 kg person falling at 10 m/s would have kinetic energy.

Answer choices: the same, 2 times more, 2 times less, 4 times more, 4 times less.

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?
