Complete the data table using the procedure above and the video provided. Using the equation v = fƛ, determine the wave speed for each trial.
Determine an average wave speed by averaging the wave speeds you found for each trial.
To calculate the exact value for the speed of sound, use the temperature given at the beginning of the video and the following equation: Vsound = 331 m/s + 0.6(TCelcius)
How close was your average speed to the calculation of the actual value for the speed of sound in m/s? Give 2 examples of errors that may have occurred during the lab that could have caused your value to be different than the value that you determined using the equation.

In the future, people will only enjoy one sport: electrodisc. in this sport, you gain points when you cause metallic discs hovering on a field to exchange charge. you are an electrodisc player playing the popular four disc variant. the disks have charges of qa = −8.0 µc, qb = −2.0 µc, qc = +5.0 µc, and qd = +12.0 µc. (1) you bring two disks together and then separate them. you measure the resulting charge of these two disks and find that it is +5.0 µc per disk. which two disks did you bring together? (a) a and b (b) a and c (c)a and d (d)b and c(e) b and d (f) c and d. (2) you bring three disks together and then separate them. you measure the resulting charge of these three disks and find that it is +3.0 µc per disk. which three disks did you bring together? a, b, and c (a) a, b, and d (c) a, c, and d (d) b, c, and d. (3) given the resulting charge of each disk measured in (b) is +3.0 µc, how many electrons would you need to add to a disk of this charge to electrically neutralize it? electrons
