Solve the following problem:
Problem: Reptiles don't use enough metabolic energy to keep their body temperature constant. They cool off at night and must warm up in the morning sun. Suppose a 2.6-m-long, 60-cm-wide, 365kgalligator is basking in the sun.
Part I: If the sun's intensity on the back of the alligator is 500 W/m2, and if energy losses can be ignored, how long will it take the alligator to warm up from 23oC to a more favorable 30oC? The average specific heat of body tissue is 3400 J/kgK.
I need tutor help to solve the above problem and express your answer to two significant figures and include the appropriate units.
