Using the liquid drop model, plot on the same graph, as a function of a, in units of mev/nucleon (a) the bulk volume binding energy per nucleon, (b) the negative of the surface binding energy per nucleon, (c ) the negative of the asymmetry contribution per nucleon, (d) the negative of the columbic contributing per nucleon, and (e) the total binding energy per nucleon ignoring the pairing terms. for a given a value, use z determined from eq. (3.18) for the most stable member of the isobar z(a)2

The uniform slender bar rests on a smooth horizon- tal surface when a force f is applied normal to the bar at point a. point a is observed to have an initial acceleration aa of 20 m/s2, and the bar has a corre- sponding angular acceleration of 18 rad /s2. deter- mine the distance b.

The amount of potential energy possessed by an elevated object is equal to what?

Researchers conducted an experiment to identify the effects of three different hand sanitizers on the growth of bacteria. the researchers grew one type of bacteria in twenty-four identical covered petri dishes. then, they opened eighteen petri dishes and applied the three hand sanitizers to six petri dishes each. they left the remaining six petri dishes closed as a control group. when the researchers measured the growth of bacteria two days later, the six dishes that had no hand sanitizer showed the least amount of bacterial growth. the researchers concluded that not using any hand sanitizer would lead to the least bacterial growth. which statement best explains why the researchers’ conclusion was not justified? the experiment tested too many variables. the control group was not treated the same as the experimental group. the sample size of twenty-four petri dishes is not large enough. the single type of bacteria is not adequate to make any conclusions.
