A small cockroach of mass 0.00030 kg is caught in the spiders web. The web vibrates at a frequency of 10.0 Hz.? What is the spring constant for the web? Unit= N/m

1.18

Explanation: The formula I used is:

f=1/(2pi) times the square root of k/m

F is the frequency, in this problem, 10 Hz.

K is the spring constant.

M is the mass.

So plugging everything in we would have:

10=1/(2pi)•sqrt x/0.00030

The answer I got was 1.18

First figure shows the object position

Second shows the image position

Third shows the focal length.
