Una cuerda horizontal puede transmitir una potencia máxima Una cuerda horizontal puede transmitir una potencia máxima, P (sin romperse) si por ella viaja una onda con amplitud A y frecuencia angular W. Para aumentar esta potencia máxima, un estudiante dobla la cuerda y usa esta “cuerda doble” como medio. Determine la potencia máxima que se puede transmitir a lo largo de la “cuerda doble”, si supone que la tensión en las dos hebras juntas es la misma que la tensión original en la cuerda individual.

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
