Sabiendo que la velocidad del sonido en el aire es de 340 m/s a 20°C, encuentre la longitud de onda del sonido Que emite un diapasón que tiene la frecuencia de 400 Hz. Recuerde que Hz = ciclos/seg.

DATOS FORMULA SUSTITUCION RESULTADO

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
