The nuclear binding energy may be approximated by the empirical expression b(a, z) a1a-az4/-0322 a1/3-a(a-22)a (a) explain the various terms in this expression. (b) considering a set of isobaric nuclei, derive a relationship between a and z for naturally occurring nuclei. (c) use a fermi gas model to estimate the magnitude of a,. you may assume a nuclear radius is r roa/s. 22 and that the

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
