If $M(A,Z)$, $M_p$ and $M_n$ denote the masses of the nucleus, proton and neutron respectively and $BE$ represents its binding energy in $MeV$, then:

The voltage gain of an amplifier with $9\%$ negative feedback is $10$. The voltage gain without feedback will be:

If the lattice parameter for a crystalline structure is $3.6\text{A˚}$, then the atomic radius in an fcc crystal is:

The circuit shown is equivalent to:

A p-n photodiode is made of a material with a band gap of $2.0\text{eV}$. The minimum frequency of the radiation that can be absorbed by the material is nearly:
