Determine the electrical force of attraction between two balloons that are charged with the opposite type of charge but the same quantity of charge. The charge on the balloons is 1.2 x 10-8 C and they are separated by a distance of 0.40 m. 2.

Mass the Alka-Seltzer tablet then put the flask on the scale to record the mass‚ and zero the scale. 2. Add 50 mL of water to the flask and record the mass. Subtract the mass of the flask from the mass of the water in the flask to find the total mass of the water. Next mass the balloon. Add together the mass of the water and tablet 3. Break

The scissors are to be passed to another student in the group and directed to: -Cut the end of the water bottle. -Cut the neck off a large balloon. Have someone hold the plastic bottle. Then stretch the balloon over the cut end of the bottle. IV. The last student in the group will be directed to:

Step out into the cold weather to get hair cold. 3.) Rub the balloon on your hair to create a static charge. 4.) This causes your hair to stand out on end. 5.) In order to decrease the static charge put some water drops on the balloon. 6.) Again rub it on your hair. 7.) The strands

Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules change

Frank Luke Jr. "He was the most daring aviator and greatest fighter pilot of the entire war. His life is one of the brightest glories of our Air Service. He went on a rampage and shot down fourteen enemy aircraft‚ including ten balloons‚ in eight days. No other ace‚ even the dreaded Richthofen‚ had ever come close to that." ~ Eddie Rickenbacker Frank Luke Jr. was born May 19‚ 1897 in Phoenix‚ Arizona and would live not only to become an Arizonan Hero but a true American Hero.

Floating Balloon Purpose : To demonstrate the principle of buoyancy of warm air. Additional information : The density variation between warm and cool air can be used to explain why warm air possesses higher buoyancy. As hot air contain atoms and molecules with higher kinetic energy than cold air‚ it has a lower density and rises up while the colder air goes downwards
