All spiders are very sensitive to vibrations. An orb spider sits at the center of its web and monitors radial threads for vibrations created when an insect lands. Assume that these threads are made of silk with a linear density of 1.0 x 10-5 kg/m under a tension of 0.40 N. If an insect lands in the web 30 cm from the spider, how long will it take for the spider to find out

The time taken by spider to catch insect 1.5 ms

Explanation:

Given:

Linear mass density

Tension on the string N

Distance between web and insect lands m

From the formula of velocity in string,

First find the velocity and then find time,

The time taken is given by,

    sec

    ms

Therefore, the time taken by spider to catch insect 1.5 ms

causes

fossil fuels burn

cities become more industrialized
