According to Wein's displacement law

Three different objects $m_{1}, m_{2}$ and $m_{3}$ are allowed to fall from rest and from the same point $O$ along thrce different frictionless paths. The speeds of the three objects, on reaching the ground, will be in the ratio of

The potential barrier, in the depletion layer, is due to

Length cannot be measure by

If vectors $\vec{P}=a\hat{i}+a\hat{j}+3\hat{k}$ and $Q=a\hat{i}-2\hat{j}-\hat{k}$ are perpendicular to each other, then the positive value of $a$ is

A particle starts from rest and has an acceleration of $2\, m / s ^{2}$ for $10 \,sec$. After that, it travels for $30\, sec$ with constant speed and then undergoes a retardation of $4 \,m / s ^{2}$ and comes back to rest. The total distance covered by the particle is
