One. Electron in each atom ... So. I think answer will be three ... I didnt think of the number of electrons but i thought of only possibilities

In a hydrogen atom energy of k level is -13.6eV L level is -3.4eV M level is -1.5eV Now if electrons dexcite from M level then there is possibility for the three values of the energy of photons released...

Homework Statement Three photons coming from excited atomic hydrogen sample are picked up. Their energies are 12.1 eV, 10.2 eV and 1.9 eV. These photons must come from? A)two or three atoms B)single atom C)three atoms D)two atoms The Attempt at a Solution By solving it i got single...

A ball of mass 'm' drops from a height 'h'. Which sticks to a massless hanger after striking it .. Neglect overturning. Find out maximum extension in rod, assuming that the rod is massless..

Then is the fourth option correct? If so why?

Ohh! I got it.. Thank you

"Is kept". Means. "Is placed"

Reason? Ok then how can u support your statement? Reason for being at rest?

Ok then how can u support ur statement ? Reason?

I thought that the first option was wrong as while rotating,,,,... when kept on rough surface due to frictional force it leads to translation

Which of the following statements are true?? OPTIONS: A)a rotating ball is kept on a rough inclined plane.It may remain at rest till it is rotating. B)A rigid body rolls up an inclined plane without sliding. The friction force on it will be upwards. C)A rigid body rolls down an...

K thanks for ur suggestion i will try to solve the problem

Find moment of inertia of a uniform quarter disc of radius R and mass M about an axis through its centre of mass and perpendicular to its plane ... I tried in the following way: I considered the relation. I= Icm + Md2 Where d is the distance between required axis and centre of...

Kirchoff law can be applied separately to any number of loops and solve then separately to find currents

V=ir. R means effective resistance "i"means total current through the cell. And then divide current into the branches of circuit in corresponding ratios.
