An electron in a hydrogen atom is in the n 3 state. a. find the energy of the electron (in ev) b. including the effects of spin, what is the total number of degenerate states with this energy? c. make a table listing the quantum numbers n, l, and m (i. e., do not include ms) of each of these degenerate states for n = 3. indicate the spectroscopic label that would apply to each state d. make an energy level diagram showing the first three states (n 1,2,3) and the different values of l, (do not include spin effects) and show all the allowed transitions

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

measure their densities same density, same sub

d) physical means can be used to separate the components of air.

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
