Write down the wavefunctions of the first 5 states of the hydrogen atom, 00, 200, b210, v21+1. for every state find whether it is even or odd in , y, and z. you may use 2 r sin cos y=rsin0sin zr cos (d) consider a hydrogen atom in an exited state n = 2. the possibility exists that after a certain amount of time, it will spontaneously emit a photon and decay back to the state 00 the rate a of this emission is 3 3teohc where p is the electric dipole moment: p q (b|r |be), and wo the lifetime of the 21m) states by calculating aj21m)+|100) hint: remember that (ee-ea)/h. find ei e-io ei ei cos sin and 2i 2 dr n! /a"1

The ballistic pendulum was invented in 1742 by english mathematician benjamin robins. it consists of an initially stationary pendulum that moves after being struck by a bullet, and it is used to measure the original velocity of the bullet. the known variables are the bullet's mass m, the pendulum's mass m, and the height to which the block and bullet swing, determined by the length of the pendulum l and final angle θ. two principles of physics are necessary to solve for the bullet's original velocity. what are these principles? conservation of momentum and newton's third law conservation of energy and conservation of angular momentum grade summary deductions 0% potential 100% conservation of momentum and newton's second law. newton's second law and conservation of angular momentum. conservation of energy and newton's third law conservation of momentum and conservation of angular momentum. conservation of momentum and conservation of energy conservation of energy and newton's second law.

The particles of an ice cube at 0°c (represented by the blue circles) come in contact with the particles of juan’s hand at 37°c (represented by the orange circles). which diagram correctly represents the temperature of the two substances and the direction of heat flow?

Acharge of 8.4x10^-4 c moves at an angle of 35 degrees to a magnetic field that has a field strength of 6.7x10^-3 t. if the magnetic force is 3.5 x10 ^-2 n, how fast is the charge moving?
