The normalized ground-state wavefunction of a hydrogen atom is ( )r a (1/ ) e r a 0 3 1/2 / ψ 0 = π − where a0 = 53 pm (the Bohr radius) and r is the distance from the nucleus. (a) Calculate the probability that the electron will be found somewhere within a small sphere of radius 1.0pm centred on the nucleus. (b) Now suppose that the same sphere is located at r = a0. What is the probability that the electron is inside it? You may approximate the probability of being in a small volume δV at position r by ( )r V

Scott’s bank account showed a balance of $750 on sunday. during the next five days, he made one deposit of $140 and numerous withdrawals of $180 each. let x represent the number of withdrawals that scott made. write an inequality that can be used to find the maximum number of withdrawals that scott could have made and maintain a balance of at least $100. do not use a dollar sign ($) in your response.
