"El sonido" 1_ Una onda sonora se produce durante 0.5 s. Posee una longitud de onda de 0.7 metros y una velocidad de 340 m/s.

¿ Cual es la

frecuencia de la onda?

¿ cuantas ondas completas se emiten en tal

intervalo de tiempo?

¿ luego de 0.5 segundos a que distancia se

encuentra al frente de la onda sonora?

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
