A transverse wave produced near one end of an extremely long vibrating string is described by the equation below. (Ignore wave reflections from the other end of the string, which is extremely far ahead.) The linear density of this string is 0.0073 kg/m. What must be the tension applied to this string?Between 350 N and 400 N.
Between 250 N and 300 N.
Between 400 N and 450 N.
Between 150 N and 200 N.
Between 300 N and 350 N.
Between 100 N and 150 N.
Between 200 N and 250 N.

A100 kg running back runs at 5m/s into a stationary linebacker. it takes 0.5 for the running back to be completely stopped

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

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
