A 10-N block and a 1-N block lie on a horizontal frictionless table. To
provide them with equal horizontall acceleration, we would have to

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
