A illustrates 2 resistors in a parallel circuit.
Take 320 and divide by 8
320/8 = 40 mi/hr or A
(d) Acceleration is a vector quantity
The speed of light is determined by the medium (material) through which the light is travelling. Light travels faster in a vacuum than it does in any other medium. Light changes speed as it passes from one medium to another. This is called refraction.
