A sinusoidal wave of angular frequency 1,203 rad/s and amplitude 3.1 mm is sent along a cord with linear density 3.9 g/m and tension 1,871 N. What is the average rate at which energy is transported by the wave to the opposite end of the cord? Give SI unit.

18.7842493212 W

Explanation:

T = Tension = 1871 N

= Linear density = 3.9 g/m

y = Amplitude = 3.1 mm

= Angular frequency = 1203 rad/s

Average rate of energy transfer is given by

The average rate at which energy is transported by the wave to the opposite end of the cord is 18.7842493212 W

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
