Write a summary paragraph discussing this experiment and the results. Use the following questions and topics to help guide the content of your paragraph. Explain the behavior of the balloons referencing the charges.
Explain how the distance and direction of John Travoltage's finger effects the spark to the door knob.
Dust in homes often clings to furnishings due to electrostatic interactions. Using principles from this lab and your reading, describe how you think the tiny dust particles acquired a charge.

50 points for who answers.

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )

explanation:

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.

that the claims meet official rules.

don't misinterpret the claims
