River Boat Vectors and Projectiles
Suppose the motion of the river boats below. Within that case, the boat is heading across the river. Inside the top case, the presence of a current causes the boat to travel downstream as it at the same time moves across the river; the result is in which it reaches the opposite shore at a point downstream from whereas it begins. In the bottom case, the absence of a current means in which the boat moves straight across the river; it ultimately reaches a point on the opposite shore directly across from whereas it begins. It is significant to note that the current is what carries the boat down the stream; it is not the motor of the boat in which gives its downstream motion.
Can several fibers gives the same amount of light? No, some fibers do not give similar amount of light. If a no. of fibers or light guides are coupled similar illuminator, this
