CBSE Class 12-science Answered

Topics of wave optics like doppler effect ,fresnel distance are not mentioned in syllabus of class 12 cbse boards 2019-2020 So that means they are not in syllabus ? Am I right

The doppler effect is the sub-topic of reflection and refraction of plane waves using Huygen's principle. So it's important topic from board exam perspective. Also, diffraction pattern given by Fresnel is important. So,do not skip these topics. These topics are important as far as your board exams and competitive/entrance exams are concerned.

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?
