Un gas experimenta el proceso termodinámico ACB mostrado en el gráfico P-V. Si el sistema absorbe 400J de calor, calcula: El trabajo realizado al pasar del estado A al estado C

What is the kinetic energy of a 10-kg bicycle moving at 10 m/s

A1kg cart slams into a stationary 1kg cart at 2 m/s. the carts stick together and move forward at a speed of 1 m/sl. determine whether kinetic energy was conserved in the collision. use the law of conservation of energy to explain the collision

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present
