¿Cuál es la producción de potencia de una mosca de 1.4g que camina en línea recta hacia arriba por el vidrio de una ventana a 2.3 cm/s?

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
