- A small fly of mass 0.667 g is caught in a spider's web. The web oscillates predominantly with a frequency of 3.43 Hz. At what frequency (in Hz) would you expect the web to oscillate if an insect of mass 0.477 g were trappedA mass (100 g) rests on a second mass (850 g) that is attached to a spring with k = 75.0 N/m. The coefficient of static friction between the two mass is 0.70. The masses are set into motion that is simple harmonic on a frictionless surface. a. What is the maximum amplitude the oscillation can have without the masses slipping against each other? b. What is the speed of the masses when they pass through the equilibrium position for the amplitude computed in part a?Problem 12 When an insect ventures onto a spiderweb, a slight vibration is set up alerting the spider. The density of spider silk is approximately 1.3 g/cm³, and its diameter varies considerably depending on the type of spider, but 3.0 µ m is typical. If the web is under a tension of 0.50 N when a small beetle crawls onto it 25 cm from the spider, how long will it take for the spider to receive the first waves from the beetle?

The steel wire has a length of 0.500 m and a mass of 3.75 g Part A What is the frequency f1 of the string's fundamental mode of vibration? Part B What is the number n of the highest harmonic that could be heard by a person who is capable of hearing frequencies up to f = 16 kHz?A siren starting from rest slides down a tall frictionless hill towards a biker. The biker travels at a constant velocity while the siren approaches him from behind. At the bottom of the hill, the siren will be traveling faster than the biker. How will the frequency of the siren change over time? It will start off lower than the original frequency of the siren, and increase in frequency'until it is higher than the original. It will be exactly the same original frequency emitted by the siren, for the entire time the siren rolls down the hill. It will be lower than the original frequency emitted by the siren, for the entire time the siren rolls down the hill. It will be higher than the same original frequency emitted by the siren, for the entire time the siren rolls down the hill.B. E. 0.2727 m 0.3140 m 0.3497 m 0.3087 m C.
