When synapsis is complete all along the chromosome, the cell is said to have entered a stage called
When $a$ ball is thrown up vertically with velocity $v_0$, it reaches a maximum height of $h$. If one wishes to triple the maximum height then the ball should be thrown with velocity
Two infinitely long parallel conducting plates having surface charge densities $+\sigma$ and $-\sigma$ respectively, are separated by a small distance. The medium between the plates is vacuum. It $\varepsilon_{0}$ is the dielectric permittivity of vacuum, then the electric field in the region between the plates is:
