Responder:
E = 1440 kJ
Explicación:
Se da que,
La potencia de un horno de cocción es de 800 W
El voltaje al que se opera es de 230 V
Tiempo, t = 30 minutos = 1800 segundos
Necesitamos encontrar la energía eléctrica utilizada por el horno de cocción. El producto de la potencia y el tiempo es igual a la energía consumida. Entonces,
Answer:
critical angle is the angle of incidence in optically denser medium, for which the angle of reflection in the less denser medium is 90 degree
Explanation:
total internal reflection occurs at one particular angle of incidence where the reflected ray lies on the boundary.
this angle is called the critical angle
I think it's 1.03412969 or 1.03
The type of investigation is she is conducting by determining the period in which it is from is referred to as the geologic age.
<h3>What is Geologic age?</h3>
This is defined as the time period in which the fossil was present on the earth and can be done using various methods such as radiometric dating methods etc. The age gotten will help scientists to ascertain different information about the organism in this context.
Fossil on the other hand which is the remains of organisms preserved in the earth crust can be studied to find out the differences in the features of organisms and how they were able to adapt to the changing environmental conditions.
