The classical speed of an electron is similar to the speeds given in the previous problem. For example the classical speed of an electron in the ground state of a H atom is 220 km/s. The uncertainty in positions given in the last problem are on the order of the sizes of atoms. What does this suggest for electrons in atoms

Anne applies a force on a toy car and makes it move forward. what can be said about the forces acting on the toy car at the moment anne applies the force?

Explain vector addition, triangle method and parallelogram method

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?
