Calculate the probability of fi nding an electron that is described by this wavefunction in a volume of 1.0 pm3 (i) centered on the nucleus, (ii) at the Bohr radius, and (iii) at twice the Bohr radius. (b) Construct an expression for the radial distribution

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.

How many 3-digit numbers can you write using only digits 1 and 7? (of course, digits can repeat.) how many 3-digit numbers can you write using only digits 1 and 7? (of course, digits can repeat.)

Which shows one way to determine the facts of x3+4x2+5x+20 by grouping
