, An electric BULB is rated as 230 V AC, 100 W ( This is called rating of bulb i.e 100 W,). if this bulb is given supply of 230 V AC it will dissipate 100 W energy in one hour. Now as per ohm’s LAW - V=I * R and power P = V * I so, p = V* I = V * V/R = V.V/R = I * I * R = I.I.R so Resistance of the bulb R = V.V/P = 230 *230/100=529 OHMS so rated current I = V/R = 230/529 = 0.434 Amps Now suppose if voltage available is 200 V then P = V*V/R= 200 * 200/529 =75.6 W ( this is power dissipation at input voltage of 200 V)

oobydoobydoo LOL no the ANSWER is a HELPS

: A column of water that is 10 feet in HEIGHT and 1 inch square weighs 4.3 pounds, the fluid PRESSURE at a DEPTH of 10 feet of water is 4.3 pounds square inch. ... Gases, LIQUIDS andfluids are all the fluids that have the ability to flow which exert BUOYANT forces that multiply forces.

n of water that is 10 FEET in height and 1 inch square weighs 4.3 pounds, the fluid pressure at a depth of 10 feet of water is 4.3 pounds square inch. ... Gases, liquids and FLUIDS are all the fluids that have the ABILITY to flow which exert BUOYANT forces that multiply forces.

e due to a liquid columnLet h be the height of the liquid column in a CYLINDER of cross SECTIONAL area A. If ρ is the DENSITY of the liquid, then weight of the liquid column W is given byW = mass of liquid column � G = AhρgBy definition, pressure is the force acting per unit area∴ Pressure =  weight of liquid column / area of cross section= Ah g / A= hρg

ics was one of my FAVOURITE subjects back in lower classes.so you have already learnt 1-D / linear motion in CLASS 9th.so the part which is DIFFICULT is 2-D.now what I will suggest you is to understand the concepts of angles, directions, application of gravity and most IMPORTANTLY components of vector and its magnitudes. the topics may sound really easy and you think you know them,but believe me there's more to it than you think.

plating is the process of plating one metal onto another by hydrolysis, most commonly for DECORATIVE purposes or to prevent corrosion of a metal. There are also specific types of electroplating such as copper plating, silver plating, and chromium plating.Electroplating involves passing an electric current through a solution called an electrolyte. This is DONE by dipping TWO terminals called electrodes into the electrolyte and connecting them into a circuit with a battery or other power supply.methods for PREVENTING corrosion:TURN to non-corrosive metals such as aluminum and stainless steel.Keep the area around the metal surface dry.Use drying agents and moisture barrier products

depends on the context of your question. If you're being introduced to General Relativity, then you're just going to assume, in the spirit of the equivalence principle, that gravity and the acceleration cannot be told apart from the pendulum's standpoint, so the acceleration is OBVIOUSLY $a+g$.If you need to do it from first PRINCIPLES in a Newtonian setting, draw a FREE body DIAGRAM of the bob. First, let's do the unaccelerated pendulum.

We should CONSIDER TWO cases:For refraction at first surface A:U= -∞μ1=1μ2=?A) when focused on surface V=2rR=rμ2/V- μ1/u= μ2-μ1/Rμ2/2r = μ2-1/rμ2= 2μ2-2μ2= 2B) When focused at centre  u= r1R=rμ2/V - μ1/u= μ2-μ1/Rμ2/R = μ2-1/rμ2= μ2-1Which is not possiblehence it cannot FOCUS at centre

R1=R2=10cm t=5cm u= - ∞For first refraction at A μg/V-μa/u= μg-μa/R1 1.5/V-0=1.5/10 v=30cm for second refraction at B u= 30-5=25cm (virtual object) R2= - 10cm 1/v-15/25= -0.5/-10 v= 9.1cm So the IMAGE is FORMED 9.1cm from the Second surface of lens

Is HereThe BERNOULLI Equation for an. INCOMPRESSIBLE, Steady FLUID Flow. In 1738 Daniel Bernoulli (1700-1782) formulated the famous equation for fluid flow that BEARS his NAME. The Bernoulli Equation is a statement derived from conservation of energy and work-energy ideas that come from Newton's Laws of Motion

rninghope the answer help youUranium is a CHEMICAL ELEMENT with symbol U and atomic number 92. It is a silvery-grey metal in the ACTINIDE series of the periodic table. ... The most common isotopes in natural uraniumare uranium-238 (which has 146 neutrons and accounts for over 99%) and uranium-235 (which has 143 neutrons).thanks

nic chemistry, the hydroboration–oxidation REACTION is a two-step organic reaction that converts an alkene into a NEUTRAL alcohol by the net addition of water across the double bond. The HYDROGEN and hydroxyl GROUP are added in a SYN addition leading to cis stereochemistry

ectric bell is SWITCHED on an electric CURRENT passes to the electromagnet and as when a conductor GETS electric current it gets magnetised and so the IRON strip gets attracted as iron strip is a magnetic material

alternating voltage is APPLIED across series RLC circuit, as the voltage is CONSTANTLY changing, the elements constantly stores and releases the energy back into the circuit.But during resonance, the energy keep on resonating between the inductor and capacitor. Because of this extra ELEMENT of energy transfer on top of the supplied AC voltage, the voltage across these two elements is higher than the applied voltage
