Calculate the average orbital radius of a 3d electron in the hydrogen what is the atom. compare with the bohr radius for a n 3 electron probability of a 3d electron in the hydrogen atom being at a greater radius than the n 3 bohr electron?

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

dang that balls went far

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
