The highest registered waterfalls in the world are those of Angel Falls, which is located in Venezuela. Its longest single waterfall has a height of 807 m. If the water at the top of the falls is 18.0 ° C, what is the maximum temperature (in degrees C) of the water at the bottom? Suppose that when all the kinetic energy of the water reaches the bottom, the temperature of the water increases.

The basal metabolic rate is the rate at which energy is produced in the body when a person is at rest. A 75 kgkg (165 lblb) person of height 1.85 mm (6.07 ftft) would have a body surface area of approximately 2.00 m2m2. Part A What is the net amount of heat this person could radiate per second into a room at 17.0 ∘C∘C (about 62.6 ∘F∘F) if his skin's surface temperature is 31.0 ∘C∘C? (At such temperatures, nearly all the heat is infrared radiation, for which the body's emissivity is 1.0, regardless of the amount of pigment.) Express your answer with the appropriate units. HnetHnet = nothingnothing SubmitRequest Answer Part B Normally, 80%% of the energy produced by metabolism goes into heat, while the rest goes into things like pumping blood and repairing cells. Also normally, a person at rest can get rid of this excess heat just through radiation. Use your answer to part A to find this person's basal metabolic rate…
A metal rod is 10 cm long and has a diameter of 2 cm one end is in contact with steam at 100 deg C while the other end contacts a block of ice at 0 deg C. The cylindrical surface of the rod is carefully insulated so heat flows only from one end to end. In a time of 20 minutes, 320 grams of ice melts. What is the thermal conductivity of the metal?
