a red led has the following specification: maximum forward current:50 ma. typical forward voltage: 1.9 v. design, sketch and label a christmas light set using 75 of these leds and an appropriate resistor connected to 120 v, 60hz power source. you need not show all the leds in your sketch. specify the value of the resistor

Objects a and b are visible in the night sky. six months later they are still visible, but object b shows less parallax than object a. which object is closer? a. a b. b c. you would need to wait another six months in order to figure this out. d. you would need to know the objects' angular diameters in order to figure this out.
