. 2. El calor específico de un líquido es de 4186 j/kg. K. Su masa es de 100g. ¿Qué cantidad de calor hay que retirar del líquido para enfriarlo desde 305,15K hasta 293,15 K?C

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

If a simple machine reduces the strength of a force, what must be increased?
