Hello everyone we are going to understand this question here given in the question given mass of man it is given m mass of man it is represented by m which is given 65 kg 65 kg and time to sleep time to sleep t1 is given 8 hour time to light course time to light course, that is given 3 .0 hour and time to slowly walk, time to slowly walk, that is, sorry, it is t2, and time to slowly work, it is represented by t3, that is one hour and jogs at the time for jogging, time for jogging, left it is represent.
01:44
By t4 which is 0 .5 hour and we have to find the change in internal energy during this process we have to find change in internal energy of the man internal energy of man we have to find this we know that energy consumed in sleeping energy consumed in sleeping e1 is 80 zhore second and energy consumed in light course activity energy consumed in light course activity in light course activity that is represented by e2 which is given 230 jule per second energy consumption energy consumption in walking, energy consumed in walking, it is represented by e3, which is given 230 jol per second and energy consumed in jogging, energy consumed in jogging that is represented by e4 which is 465 joules per second.
04:20
Now we know that we know that 1 hour is equal to 6 minute 60 minute into 60 second or we can write 3 ,600 second.
04:34
Now we know that total energy, total consumed energy in the activity, in the daily activity, that is even total here 80 into daily 8 hour is spending plus, plus 230 into 3 hour daily spend and 230 into 1 hour plus 0 .5 into 465.
05:31
Here we have already converted power into second.
05:34
So after doing the further calculation we will get 6 .45 into 10 to the power 6 jule.
05:41
Now we know that total internal energy is equal to energy consumption daily work...
