Example #6: A metal cup of surface area 200. cm- needs to be electroplated with silver to a thickness of 0.200 mm. The density of silver is 1.05 x 104 kg m 3 The
mass of a silver ion is 1.79 x 10-25 kg and the charge is the same magnitude as that on
an electron. How long does the cup need to be in the electrolytic tank if a current of
12.5 A is being used?

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?

Avolleyball player hit a ball with a mass of 0.25 kg. the average acceleration of the ball is 15.5 m/s². how much force did the volleyball player apply to the ball? 62.0 n 3.87 n 62.0 m/s² 3.87 m/s²
