The temperature of inversion of a thermocouple is 620°C and the neutral temperature is 300°C. what is the temperature of cold junction ?

A photosensitive metallic surface has work function, hv0. If photons of energy 2hv0 fall on this surface, the electrons come out with a maximum velocity of 4 x 10^6 m/s. When the photon energy is increased to 5hv0, then maximum velocity of photoelectrons will be :

Fission of nuclei is possible because the binding energy per nucleon in them :

Application of a forward bias to a p-n junction :

The displacement x of a particle varies with time t as x = ae^(-αt) + be^(βt), where a, b, α and β are positive constants. The velocity of the particle will :
