In Bernoulli's equation, why the work on fluid at the lower end of the pipe is taken as negative?
please explain why the force is negative to displacement at the lower end?
What is electron affinity??
Q: Why energy is released when an electron is added to a gaseous atom?
What is electron affinity? Please explain it with reference to release of energy?
if a hard sticky mud ball is trown on a wall it sticks to it
it is an inelastic collision
K.E. is not conserved
but here momentum is also not conserved because mud had an initial velocity
so initial momentum of mud + initial momentum of wall (that is 0) = initial momentum of mud

in a battery, when all the electrons have transferred to the positive terminal ( i mean both terminals have same no. of electrons) , then do any current flow? if no , then how much time does it take for all electrons to be transferred fron negative to positive terminal? (i know it is a silly...
