Only question 63 62. A spider spins a web with silk threads of density 1300 kg/m³BIO and diameter 3.0 μm. A typical tension in the radial threads ofsuch a web is 7.0 mN. Suppose a fly hits this web. Which will reachthe spider first: the very slight sound of the impact or the disturbancetraveling along the radial thread of the web?63. III In 2003, an earthquake in Japan generated 1.1 Hz wavesINT that traveled outward at 7.0 km/s. 200 km to the west, seismicinstruments recorded a maximum acceleration of 0.25g alongthe east-west axis.a. How much time elapsed between the earthquake and the firstdetection of the waves?b. Was this a transverse or a longitudinal wave?c. What was the wavelength?d. What was the maximum horizontal displacement of theground as the wave passed?64. III A coyote can locate a sound source with good accuracy byBIO comparing the arrival times of a sound wave at its two ears.Suppose a coyote is listening to a bird whistling at 1000 Hz.The bird is 3.0 m away, directly in front of the coyote's rightear. The coyote's ears are 15 cm apart.a. What is the difference in the arrival times of the sound at theleft ear and the right ear?b. What is the ratio of this times difference to the period of thesound wave?Hint: You are looking for the difference between two numbers thatare nearly the same. What does this near equality imply about thenecessary precision during intermediate stages of the calculation?65. Il A wave travels along a steel string with a speed of 22 m/s. At70.7172IN73BI
