An electron initially at rest recoils after a head-on collision with a 5.94-keV photon. Determine the kinetic energy acquired by the electron. (In a head-on collision, the photon has a scattering angle of ? = 180°.)
What is potential barrier for the molecule aggregation? Will the solution be stable at these conditions? Will it be stable at 100 mmol/L salt concentration?
An elevator cable can withstand a maximum tension of 19,500N before breaking. The elevator has a mass of 480 kg and a maximum acceleration of 2.24 m/s2. Engineering safety standards require that the cable tension never exceed two-thirds of the breaki..

A 2.03 kg book is placed on a flat desk. Suppose the coefficient of static friction between the book and the desk is 0.602 and the coefficient of kinetic friction is 0.327. How much force is needed to begin moving the book
A space craft with a mass equal to .25 x Mmoon is in orbit about the sun with a period of 3 years. What force would the space craft exert on the Earth
The activation energy for vacancies in Cu is w.28 eV. Find the fractional number of vacancies at the melting temperature. Estimate the contribution of vacancies to the thermal expansion at the melting temperature.
A supertrain of proper length 97 m travels at a speed of 0.91c as it passes through a tunnel having proper length 50 m. As seen by a trackside observer, is the train ever completely within the tunnel? Yes No If so, how much room does it have to spare..
Compare how Helmholtz free energy describes any change in a system that takes place at constant temperature T and how Gibbs free energy describes any change that takes place at constant temperature T and pressure P. In each case, what happens if no n..
