Astudent is examining a chemical reaction. the student notes that the reaction requires 7.14 kcal/mol of energy per biomolecule synthesized. the reaction itself produces 21.42 kcal/mol of energy. the student argues that this is enough energy to make 3 of the biomolecules. what error has the student made in the analysis?

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

For general projectile motion, when the projectile is at the highest point of its trajectory, its acceleration is zero? a)the horizontal and vertical components of its velocity are zero. b) its velocity is perpendicular to the acceleration. c)the horizontal component of its velocity is zero. d)its velocity and acceleration are both zero.
