All of the following are specific requirements for energy in biochemical processes except:
A. Release of energy from storage must occur at a carefully controlled rate.
B. Release of energy from food must occur gradually.
C. Stored energy must be in a form that is chemically accessible.
D. Energy needed for unfavorable reactions must be available in the form of heat.
E. The correct amount of heat must be released from biochemical reactions to maintain body temperature.
Use the recurrence relation for the radial wave function to construct the n=3n=3n=3 radial states of hydrogen. Calculate the normalization constant for the R32(r)R_{32}(r)R32(r) state.
A tie of uniform width is laid out on a table, with a fraction of its length hanging over the edge. Initially, the tie is at rest. What is the coefficient of static friction between the tie and the table if the tie begins to slide when one-fourth of its length hangs over the edge?
