La distancia entre un objeto real y la imágen conjuga un espejo cóncavo es 72 cm. la altura de la imágen es 1/4 de la altura del objeto. a.) Determine la abscisa del objeto
b.) Calcule la distancia focal del espejo

technology is the application of the knowledge gained by science.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

snell's law

refractve index = sin incidence / sin refraction
