Dear Student

IF the mirror is not moving observed velocity of the image= -(  2i+3j+6k)

When the mirror moving the distance decreasing with velocity i+j+k,  and the distance between image and mirror moves at the same velocity  i+j+k. So the relative distance between  Object anb image  is 2( i+j+k).

 the velocity of image as seen by a stationary
observer = - (  2i+3j+6k)+2( i+j+k).= -j-4k

CBSE 12-science - Physics
The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
