Actividad: La puerta de un horno esta hecha de vidrio (k=4.3 J/m*K*s). Tiene unas dimensiones de 100cm de alto, por 80cm de ancho y un grosor de 10 cm. si el horno esta a 180ºC y en la casa hacen 15ºC. ¿Cuanto calor pierde el horno en un segundo? si el bizcochuelo de adentro tarda 50 min en hacerse, ¿cuanto calor pierde el horno mientras se hace?

necesito resolucion urgente lo entrego el jueves a la tarde.

Activity:

The oven door is made of glass (k = 4.3 J / m * K * s). It has dimensions of 100cm high, 80cm wide and 10cm thick. if the oven is at 180ºC and in the house it is 15ºC. How much heat does the oven lose in one second? If the cake inside takes 50 minutes to make, how much heat does the oven lose while it is being cooked?

wavelength variability is the right one

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

i think it's 35 meters
