-Pressure is defined as the force applied on a unit F surface area. P = A -P = h ρ g Pressure at both side are same, P A = P B So that ; F A = F B A A A B Archimedes Principle: When an object is fully or partially immersed in a fluid, the upthrust or buoyancy on it is equal to the weight of fluid displaced. F B = Vρg In a steady flow of fluid, the _ pressure in the fluid is _decreases when the velocity of the fluid is high and vice versa. A B AND gate A B OR gate A NOT gate Y Y Y The inertia of an object is the tendency of the object to remain at rest or, if moving, to continue its motion In a swamp area, a fan boat is used. - The fan produces a high speed movement of air backward. This produces a large momentum backward. -By conservation of momentum, an equal but opposite momentum is produced and acted on the boat. So the boat will move forward. Total Momentum Before = total momentum after m 1 u 1 + m 2 u 2 = m 1 v 1 + m 2 v 2 -Radioactivity is the spontaneous and random emission of radioactive rays from unstable radioactive materials after which they become more stable The half - life of radioactive source is the time taken for half number of the nuclei in a sample of radioactive atoms to decay Specific Heat Capacity Quantity of heat energy required to raise the temperature of 1 kg of a substance by 1 0 C. State Charles law. For a fixed mass of gas, its volume is directly proportional to its absolute temperature The magnitude of the induced e.m.f in a wire can be increased by 1)Increasing the speed of the relative motion 2)Increasing the strength of the magnetic field The magnitude of the induced e.m.f in a coil/solenoid can be increased by 1)increasing the speed of the relative motion 2)increasing the strength of the magnetic field 3)increasing the number of turns of the coil Total internal reflection thongks 2016 is the complete 17 reflection of light ray travelling from a denser medium to a less dense medium..- light ray enters from a denser medium towards a less dense medium. -the angle of incidence in the denser medium is greater then the critical angle of the medium ( i > c) The principle of superposition state when two waves overlap, the resultant displacement is equal to the sum of the displacements of the individual wave. λ = ax D Depth of sea, d = v x ELECTROMAGNETISM The factors that affect the magnitude of the force on a current-carrying conductor in a magnetic field are: 1. the magnitude of the current in the conductor The greater the current the greater the force on the conductor. 2. the strength of the magnetic field The greater the magnetic field strength the greater the force on the conductor. Faraday s Law states that the magnitude of the induced e.m.f. is directly proportional to the rate of cutting of the magnetic field lines or the rate of change of magnetic flux by a conductor. 17 000014
