Explanation:
(a)
- Oxygen consumption rate of humans,

area of human skin, 
- diffusion rate through skin of humans,

- ∴


<u>Flux of diffusion rate, </u>

Answer: 1.274 N minimum force required to slide the book across the surface
Explanation:
Mass of the book = m = 0.2 kg
Normal force acting on the book,N = mg
Coefficient of friction =
= 0.65
Minimum force required to slide the book across the surface= F


1.274 N minimum force required to slide the book across the surface
The naked eye is very limited. Unlike the telescope which can see far away.
