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.
Hertz; Hz (after H. Hertz, 1857-1894) The derived SI unit of frequency, explained as a frequency of 1 cycle per s; therefore it has units of s -1 .
Reflection and Refraction Describing reflection and refraction, involving total internal reflection. You might drag the control at the top to modify the angle of incidence and

The voltage across the terminals of a cell when it is supplying current to external resistance is known as potential difference or final voltage. Potential energy dissimilarity is
Suppose you blow the top of a bottle and hear a resonance sound (standing wave). The length of the bottle is about 25cm. If the speed of sound in air is about 340 cm/sec., what i
Water accelerated by a nozzle to 20 m/s strikes the vertical back surface of a cart moving horizontally at a constant velocity of 5 m/s in the flow direction. The mass flow rate of
Production of electricity : Very large amounts of electrical energy lie dormant in the atoms of every speck of material in the universe. Whilst the atoms remain electrically ba
Explain the production of Newton's ring because of reflected light with a neat diagram. Get the expression for the diameter of both dark and bright ring.
Huygens wave theory: Huygen's wave theory is not correct in all respects. 2. It assumes simply that light energy is propagated as a wave. 3. At the time of his proposition
An e.m.f. of 25V is induced in a coil of 300 turns when the flux linking with it alters by 12mWb. Find the time, in milliseconds, in which the flux makes the change. An ignitio
