To understand this question, we have to consider the wave-particle duality of electrons. When passing through a slit, electrons exhibit a wavelike property- they diffract or spread out like a wave passing...
First, we can deduce the equation for beta-plus decay in terms of the nucleons. We know a positron, ß+ (antilepton), is produced, so to conserve lepton number an electron neutrino, ve<...
This phenomena is a result of the conservation of angular momentum: An isolated system's rotational intertia does not change.
Angular momentum is given mathematically by GLAnswered by George L. • Physics tutor2643 Views
m = 3kg ; 7kg u = 5ms^-1 ; -2ms^-1 (Taking the direction to the right as positive). momentum before = m1u1 + m2u2 = (3x5) + (7x-2) = 1 momentum after = (m1+m2)v2 = (3+7)v = 10v By the principle of conserv...
The angle at which this takes place is called the critical angle.
We can apply Snell's law in this situation: n1 sin C1 = n2 sin (90deg)
