Circuitos electrónicos y resistencia Problema 1
Al aplicar una tensión de 220voltios a los extremos de una resistencia circula una corriente de 30 amperios
Calcular
a. La resistencia del conductor
b. La potencia
c. La carga que atraviesa el conductor en 5
segundo
Problema 2
¿Cuál es la tensión (diferencia de potencial V)
necesario para que por una resistencia de 80 Ω
circule una corriente de 3 amperios?
Problema 3
Un Bombillo trae marcado en su caja los
siguientes datos 75W 60V
¿Cuál es la resistencia de su filamento?
¿Qué corriente puede soportar?
¿Qué carga lo atraviesa en 2 segundos?

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

bacteria that live on the ocean floor are sustained by phytoplankton. phytoplankton, microscopic marine photosynthetic organisms, have a vastly significant role to play not only in the marine food web of which they’re part of, but also on a more global scale. despite their infinitely small size in comparison to other marine organisms, these tiny creatures occupy an immensely important ecological niche: they are the foundation of the marine food web, and as primary producers, play key roles in supporting all other organisms in the marine environment, as well as in the regulation of the earth’s climate through the sequestration of carbon, oxygen production, and other related processes. phytoplankton account for roughly half of all global primary productivity; therefore, their significance extends far beyond the marine environment alone. there is an intriguing sense of irony in the realization that these tiny living beings that often live out their existence unnoticed and undetected by the rest of the world, have such a far-reaching impact on the lives of virtually all other living organisms on the planet, particularly on those in the marine environment. the world that we have become accustomed to has been and is continuously shaped by the workings of these miniscule yet vital “plants of the sea”.

hope this !
