Our molecular model of matter describes a fluid as consisting of lots of little particles (atoms or molecules) moving around very fast. Collisions between the molecules makes the particles of the fluid
change directions and speeds often and randomly. We've talked about two different phenomena that depend on these random molecular interactions: viscosity and diffusion. Viscosity is the way
collisions with other parts of the fluid slow down faster-moving bits of fluid, and diffusion is the way collisions spread out concentrations of molecules. Let's consider the viscosity and diffusion
coefficients might depend on the properties of the fluid by dimensional analysis

You discovered a group of people living in a primitive village
that is far from civilization. There are about 40 people living in 12
huts. Their primary source of food is from hunting beasts in the
forest, fishing in the river, and farming different crops. During
summer, they wear thin clothes to minimize the heat in their
bodies. They do not have air conditioning systems or fans that
could cool them on such hot days but they usually stay under the
trees or near the river where there is plenty of fresh air. At night,
they light a campfire to provide heat and to give a little brightness
during the dark.
Supposing you have with you motors, generators, and transformers (the
types are up to you), how would you use them to improve the quality of life
of the people in the village?

and 2 are the animals' metabolic rates and m1 and m2 are the animals' masses.
a) Compare the metabolic rates of a 70-kg man and a 15-kg dog.
b) Compare the metabolic rates of a 5-kg cat with that of a 50-g mouse.
c) Compare the metabolic rates of a 10-g hummingbird and a 5000-kg elephant.

- A woman expends 95 kJ of energy in walking a kilometer. The energy is supplied by the metabolic breakdown of food intake and has a 35 percent efficiency. If the woman drives a car over the same distance, how much energy is used if the car gets 8.8 km per liter of gasoline (approximately 20 mi/gal)?
