Consider a particle of mass m in an infinite one-dimensional well of width d. the particle is in the lowest energy state (a) what is the energy of this state? (b) the width of the well is slowly (adiabatically) increased to 2d. what is the new expectation value of energy (c) if, conversely, the width of the well is increased to 2d rapidly (suddenly), (i) what is the new expectation value of energy? i) what is the probability for the particle to remain in the ground state?

What is the scientific definition of energy that relates to work

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost
