when a electron is hit by an highly energetic photon whose energy is higher than the ionization energy such that the energy of the photon is used by the electron to get released from the atom and the remaining energy is used by the electron as kinetic energy to move energy of the photon =work function+h.v

hiesenberg said that the position and the momentum of a microscopic particle like electron cannot be determined precisely in the orbitolfor every measurement their is some uncertainity in the presence of that electron in the particular spacedelta[x].delta[p]=h/2piewhere h is the planck's constant

kwhen the spring gets compresses to the maximum extent then the body gets maximum velocity

as the total charge is -1 1+2x=-12x=-2x=-1i'm sorry for misguiding u

as the toatl charge is -1 u hve to take the sum of all the charges as -1 but not +11+2x=-1x=-1

double and triple bonds can break easily and get replaced by hydrogens or some groupswhereas single can only undergo substitution reactions

it's possible only for values greater than 1 as log[log1] is log0 which is not defined

HO2in this compoung the oxidation state of hydrogen is +1 and the total charge is -1we need to find out oxidation state of oxygenthe total charge is nothing but the algebraic sum of the charges of all the elements in a compoundlet's assume oxygens oxidation state as x then 1+x=-1so x=-2

This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]
dot product is a product of a vector with another vector in the direction of the former vector in simpler words if a man pulls a block on the ground such that the force makes an angle with the horizontal then the work done is the dot product of the displacement and the component of the force along the direction of displacement or force and component of the displacement alonf the direction of the force W=F.Scos[theta]it always give a vector as it involves magnitude of two vectors and doesn't deal with direction

it's because e to the power ifinite divided by infinite is 0as anythng divided by infinite is 0so the value of the integral is 0

is it integration or differentiationif it's integration is [x^n+1/n+1]+[x^m+n+1/m+n+1]+cif it's differentiation[n]x^n-1+[m+n]x^m+n-1

mass cant be 0 anywhere in the universe it's the individual property of an objectweight can be zero somewhere in the universe but mass cant be 0

it's not actually disappeared but it's converted into other formair in the room goes into the lungs of a man, gets heated and comes out which is circulated by the fan throught the room making the room hot
