Cow has eaten 1500 kJ of stored chemical energy in the form of food. 945 kJ is excreted as waste products. 495 kJ is ‘used’ for respiration.

a. How much of the original 1500 kJ is stored as chemical energy in the

tissues of the cow?

b. The answer to part a is all the energy that can be transferred to a human.

Calculate the efficiency of the energy transfer to the human.

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

Which accurately compares concave and convex lenses?
