Answer:
7.656 m/s
Explanation:
El sonido viaja a cierta velocidad y tiene una frecuencia y longitud de onda. La relación entre la velocidad del sonido (V), su frecuencia (f) y la longitud de onda (λ) es la misma que para todas las ondas, está dada por la ecuación:
V = fλ
pero f = 1/T
∴ V = λ/T
donde T es el período
Dado que:
período (T) es el tiempo necesario para subir y bajar = 3.2 s
La distancia entre dos crestas es la longitud de onda (λ) = 24.5 m
V = λ/T = 24.5 / 3.2 = 7.656 m/s
V = 7.656 m/s
Answer:
-34.5 W
Explanation:
rate of heat transfer = Stefan-Boltzmann constant x emissivity x surface area x temperature^4
If your asking about the total amount of time the sun is visible, it will be equal over the course of a year. In Nome, Alaska, it will be daylight almost 24 hours a day in the summer and be dark almost 24 hours a day in the winter. In San Diego they are much closer to the equator and will receive sunlight roughly the same amount each day all year long. In the end these times will add up to the same amount.
However if you are asking about intensity of sun light received, San Diego will get considerably more since its near the equator and its getting almost direct sunlight. In Nome, the sunlight is hitting the earth at an angle so fewer rays of light are hitting the ground per square foot.
