Se encuentra que dos esferas metálicas concéntricas tienen una diferencia de potencial de 900V cuando se les aplica una carga de 6.726X10–8 C. El radio de la esfera exterior es 0.210 m. ¿Cuál es el radio de la esfera interior?

I'd go for the one that says that knees are fulcrums, lower legs are levers and the ankles hold loads.hope it ,happy homework/ study/ exam!

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !

+10 that is always the common denominator
