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.
Study of a rolling ball A large ball bearing or 'bagatelle ball' rolling down a smooth track can be timed by a pendulum. To make the track, fasten together two 120 cm lengths o
Electric field (intensity) is a vector number. Electric field because of a positive particle is always away from the charge and that because of a negative charge is always toward
Why it is in general considered easier to determine the electric potential at a given point in space or at a given set of points in space due to a continuous charge distribution th

For an infinite sheet of positive charge, the electric field lines: a) Run parallel to the sheet of charge b) Are perpendicular to the sheet of charge and point in toward
Ball bearings Place some marbles in the lid of a tin on the floor. Put single foot on the marbles and notice how simply you can spin round.
LENARD ATOMIC MODEL : Lenard suggested that the atom must have a lot of empty in it. Lenard's model of an atom could not explain about the stability and mass of an atom .
A convex lens of refractive index 1.5 of focal length 0.2m is immersed in water of refractive index 1.33. Determine the focal length of lens in water.
A mild steel ring has a radius of 50mm and a cross-sectional area of 400mm 2 . A current of 0.5 A flows in a coil wound uniformly around the ring and the flux formed is 0.1mWb
Diffraction is a phenomenon that is severely associated with light. That is to utter that light and only light undergoes diffraction. (By light here we denote any form of electroma
