Find out the frequency of the fourth harmonic if the string, Ask an Expert

Academics

Q1. A person takes a trip, driving with a constant speed 86.40 km/h except for a 26 min rest stop. If the person's average speed is 79.2km/h.

how much time is spent on the trip?

Q2. Find out the frequency of the fourth harmonic if the string is fixed at one end and free at other. (That is, if the free end is attached to a long string of negligible mass.)
