En la figura se ilustran cuatro vías que un tren puede tomar. todas las vías tienen una parte curva que es parte de un círculo. En dos de las vías la parte curva corresponde a medio circulo y en las otras 2 a un cuarto de circulo
Supongamos que un tren toma en distintos momentos cada una de las vías del tren con la misma rapidez constante
Clasifica las vías de acuerdo con la magnitud de aceleración que experimenta el tren cuando va sobre la parte curve de cada vía. Indica el orden de la aceleración de mayor a menor

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.

1) a child holds two dogs on two separate leads. the dogs are pulling in different directions. one is pulling a force of 20n north and one is pulling 15n eastwards. calculate the resultant force on the child. state the direction. (use the parallelogram of forces) 2) a force of 20n acts horizontally on an object. a second force of 5n acts at 60 degrees to the first one. calculate the resultant force. worth 20 points, need answers asap with method you x
