Calculate the probability that the electron in the ground state of a hydrogenic atom of nuclear charge Z is measured to be inside the nucleus. A nucleus with A nucleons (Z protons and A-Z neutrons) has an approximate radius of r 11.2 * 10-15 m2A1>3 . Calculate the probabilities for hydrogen and uranium-238.

Joe shines white light into a bowl half full of water at an angle of incident of 27.5°. calculate the angle of refraction in the water given the indices of refraction for air and water are 1.00 and 1.36, respectively.

Plz mark brainliest 30 points1) find the momentum of a 12 kg snowball that is rolling with a velocity of 9 m/s.2) an 8 ball with a mass of .5 kg is sitting at rest. it is hit by the cue ball (1 kg) traveling at 2.5 m/s. if the cue ball is at rest after the collision, how fast is the 8 ball traveling after the collision? 3) two football players are running toward each other. if the offensive player is 75 kg and is running 8 m/s, how fast must the 60 kg defensive player run in order for the two players to hit and stop?
