Ahydrogen atom consists of a positively charged nucleus and a negatively charged electron. so, it is an electric dipole whose dipole moment is given by the product of the electron's charge and its distance from the nucleus. (a) calculate the expectation value of the dipole moment of a hydrogen atom in a stationary state vnlm in cartesian coordinates think about the physical implication of the result (b) for the state 211 calculate the expectation values of the squares of the cartesian components of the dipole moment, (d2), (d2), and (d2) you will need to express cartesian coordinates in terms of spherical polar ones, i. e r sin cos p and so on.

the answer is 46 mls because when you add the speed per second it increses the speed

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
