A husband and wife take turns pulling their child in a wagon along a horizontal sidewalk. Each exerts a constant force and pulls the wagon through the same displacement. They do the same amount of work, but the husband's pulling force is directed ${58}^{o}$ above the horizontal, and the wife's pulling force is directed ${38}^{o}$ above the horizontal. The husband pulls with a force whose magnitude is 60 N. What is the magnitude of the pulling force exerted by his wife?

Why in Compton effect an electron (which is very lightly bounded) can't absorb whole energy of incident photon but in photoelectric effect the electron absorb whole energy of the incident photon? In Compton effect the electron is not totally free, if it absorb whole energy then it does not violet the basic postulate of relativity. But in this case we consider the collision of incident photon with the free electron (though it is not completely free) is elastic. Why it is not consider here some energy (though small) loss to free the electron from the metal?

Find the de Broglie wavelength of a football of mass 0.4 kg traveling 23 m/s?

Quantum mechanics problems and solutions belong to one of the most complex aspects of Physics because it takes several disciplines to get things done. It is exactly why we have a plethora of different questions that are asked by engineers, designers, programmers, data scientists, and students who do not have sufficient skills in Physics. Take your time to study quantum mechanics examples and explore the answers that have been offered. There are also de Broglie equation problems that focus on the wave properties of matter and the nature of the electrons that will help you. If you need to experiment with the other types of Quantum Mechanics and explore the radiation physics, make sure to che
