Differentiation Class 12th Objective question BSEB CBSE ALL BOARD

A point object is placed infront of a plane mirror as shown in figure. X_(OM)impliesx - co-ordinate of object relative to mirror X_(IM)impliesx- co -ordinate of image relative to mirror X_(IM)=-X_(OM) differentiating V_(1M)=-V_(OM) V_(I)-V_(M)=-(V_(0)-V_(M)) Velocity if image relative to mirror = velocity of object relative to mirror. basing on this information answer the question Two bodies A and B are moving towards a plane mirror with speeds V_(A) and V_(B) respectively as shown in fig. The speed of image of A with respect to the body B is

A monochromatic beam of light having photon energy 12.5 eV is incident on a simple A of atomic hydrogen gas in which all almost are in the ground state. The emission spectra obtained from this sample is incident on another sample B of atomic hydrogen gas in which all atoms are in the first excited state. Based on above information, answer the following question: The atoms of sample B
