Momentum of electron=mv=6.377x10^^-24 kg m/s

λ=h/mv=6.63x10^-34/6.377x10^-24=1.039...x10^-10=1x10^-10m 

Firstly, let's move the x^​3's onto the same side (and preferably keep them positive). Let's add x^​3 to both sides, which means the RHS will now read '2x^​3 - 25' and the LHS will read '103'. Next we wan...

1. atomic radius: the larger the atomic radius, the smaller the attraction of the outer shell electrons to the nucleus so the ionisation energy is lower reduced as atomic radius increases. 2. nuclear c...

Understand the question:

'w.r.t' stand for 'with respect to', so the qestions is asking for the dericative and integral to be calcuated in terms of x - so find dy/dx and (integral sign) y dx...

Start by recognising that this is a separable differential equation; it can be written with all of the x's on one side of the equals sign, and all of the y's on the other. The first step is to rearrange s...
