Certain stars at the end of their lives are thought to collapse combining their protons and electrons together to form a neutron star. Such a star could be thought of as a giant atomic nucleus.
The winner of the competition wants to know if he has broken the world record for the break shot of 32mph (about 14.3m/s). The ball landed a distance 5.15m away from the table edge, calculate his break shot speed. At what speed did his pool shot h..
A very long solenoid of circular cross section with radius R = 5.30 cm has n = 69.0 turns/cm. An electron is sitting just outside the solenoid, at a distance r = 5.80 cm from the solenoid axis. What is the magnitude of the force on the electron as..
A certain brand of hotdog cooker works by applying a potential difference of 142 V across opposite ends of a hot dog and allowing it to cook by means of the thermal energy produced.How much electrical energy is transferred to thermal energy.
