Sobre un plano inclinado que forma 37° con la horizontal, se encuentra un bloque A, de masa 6 , unido por medio de una cuerda a otro bloque B, de masa 3 que cuelga de la cuerda, la cual pasa por una polea situada en la parte inferior del plano. Si el coeficiente de rozamiento entre el bloque y el plano es = 0.4, calcular la aceleración del sistema y la tensión del hilo.

Asmall 12.00g plastic ball is suspended by a string in a uniform, horizontal electric field with a magnitude of 10^3 n/c. if the ball is in equilibrium when the string makes a 30 ° angle with the vertical, what is the net charge on the ball?

The starship enterprise is caught in a time warp and spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. the 125-g sample was heated to 96.3°c and placed into a calorimeter containing 85.9 g of water at 20.0°c. the heat capacity of the calorimeter was 14.2 j/k. the final temperature in the calorimeter was 24.5°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.
