Question
The viscid silk produced by the European garden spider (Araneus diadematus) has a resilience of 0.35. If 10.0 J of work are done on the silk to stretch it out, how many Joules of work are released as thermal energy as it relaxes?

Answer: The energy released as thermal energy is 6.5 J
Explanation:
Energy stored by the spider when it relaxes is given by:
We are given:
Resilience = 0.35
Work done = 10.0 J
Putting values in above equation, we get:
Energy released at thermal energy is the difference between the work done and the energy it takes to relaxes, which is given by the equation:
Putting values in above equation, we get:
Hence, the energy released as thermal energy is 6.5 J
