DEC-005-02 Cuando se practica el buceo, hay que distinguir dos tipos de presión: la atmosférica (el peso del aire sobre la superficie del agua) y la hidrostática (el peso del agua sobre el buzo). La suma de las dos presiones parciales da como resultado la presión absoluta, que es la que nos afecta. Entonces, si un buzo se sumergiera a 20 m de profundidad en el mar, ¿Cuál sería su presión absoluta? (Use: pagua =1,18x103 kg/m3; Patm-D101 kPa; g=10 m/s2)

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
