All spiders are very sensitive to vibrations. an orb spider will sit at the center of its large, circular web and monitor radial threads for vibrations created when an insect lands. assume that these threads are made of silk with a linear density of 1.0 105 kg/m under a tension of 0.40 n, both typical numbers. if an insect lands in the web 30 cm from the spider, how long will it take for the spider to find out?
