As charge is quantized, the least amount of charge that can be transferred is e. According to the question, energy lost is completely transferred in the form of the photon. Please note that the energy...
dear ajay as u knows according to bohr electron moves in the orbits and its wave like fashion , and the no of wave generated will be equal to the circumference of the orbits . and its found that...
dear nithin radioactivity is a spontaneous emission of energy from an unstable atoms , there are stable atoms , which remain same always but unstable which break down or decay into new atoms . these...

mass is the physical quantity that would never cahnge whether it is on on the space or the earth. This is the only reason he writes in the paper in mass terms not weight. As weight is mg that changes...
The direction of wave is in positive direction. wavelength = 2*pi*v/w = > (3/2pi)*2*pi/(2pi * 10^8) => 3/2pi * 10^-8 Ecomponent = 0.5
T – mg = ma a = (T-mg)/m = (30.2 – 28.9)/2.89 = 0.5 m/s^2 approx. would be the accln. of the rope required to pull the 2.89 kg bucket of water.
From WET that is Work Energy Theorem, W = Change in K.E Hence, Wair res. + Wmgh = 0.5m(gh/2) – 0 Wair. res. = 0.5m(gh/2) – mgh => mgh/4 – mgh => -3mgh/4 J
Dear Arjun, according to the question and parametre sgiven, Force = kx 50 = k*0.25 * 10^-2 k = 200 * 100 N/m and Work = 0.5kx^2 obvious.
Reasons are: CBA has gain less than 1 as compare to the CEA which has gain upto 500. High input noise is also the reason which is but also immune to the noise.
Dear Sushmita, sinthetha is taken because the angular momentum is given as: L = m(v x r) hence the cross product therefore can be written as: L = mvrsintheta obvious.
Total decal constant that is, k = k1k2/(k1+k2) =>after putting the values k1 = 1620 and 405 net k = 1/324 year. N/4 would left after disintegrating three-fourth and hence, N/4 = e^-(kt) taking log...
PT = k given AND the coeff. of volume expansion of the gas is given as: Y =(1/V)(dV/dT) From ideal gas eqn., PV = nRT or kV = nRT^2 dV/dT => (2T)*(nR/k) and Y = 2nRT/kV or 2PV/kV => 2P/k => 2P/PT =>...
Becausse from Farday's law the voltage is induced due to the change in the flux of the circuit. Hence if the flux changes the emf is generated and hence the current get flows to the circuit. that is:...
This the standard eV has been defined to calculate the Energy from Planc's eqn. directly from the given thershold wavelength in Angstorm. Hence the formulae would be: E = 1242/(wavelength in Angstorm)...
All the sounds in air is vibrated and gets disturbed to each other and travel through air as medium in the form of longitudinal waves and therfore we heard voice. Hence any obstacle if found b/w the...
Already Answered: For the easeof calculation in case for diodes circuit we do short circuit for diodes when it is forward biased andd solve the question. In case of reverse bias we assume the branch...
