Un móvil parte del reposo, al llegar a los 4 segundos lleva una velocidad de 12m/s, al llegar a los 7 segundos mantiene
esta velocidad, para después al llegar a 12 segundos
disminuir a 7m/s su velocidad, y continuar con esta misma
hasta llegar a 18seg, para que a los 20seg aumente su
velocidad hasta 14m/s y luego bruscamente detenerse a los
27seg

How can you increase the strength of an electromagnet?

A47.2 g block of copper whose temperature is 480 k is placed in an insulating box with a 91.8 g block of lead whose temperature is 200 k. (a) what is the equilibrium temperature of the two-block system? (b) what is the change in the internal energy of the two-block system between the initial state and the equilibrium state? (c) what is the change in the entropy of the two-block system? the heat capacities of copper and lead are 386 j/kg·k and 128 j/kg·k, respectively.
