Una onda senoidal se propaga por una cuerda estirada en el eje x. el desplazamiento de la cuerda en función del tiempo se grafica en la figura 1 para partÃculas en x = 0 y en x = 0.09 m. a) calcule la amplitud de la onda. b) calcule el periodo de la onda. c) se sabe que los puntos en x = 0 y x = 0.09 m están separados una longitud de onda. si la onda se mueve en la dirección +x, determine la longitud de onda y la rapidez de la onda. d) si ahora la onda se mueve en la dirección -x, determine la longitud de onda y la rapidez de la onda.

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
