If you remove the cell wall from a plant cell and place it into a drop of water

A single electron orbits around a stationary nucless of charge + Ze where Z is a constant and e is the magnitude of electronic charge ,if respuires 47.2 e is excite the electron from the second bohr orbit to the third bohr orbit a. Find the value of Z b. Find the energy required to the electron from n = 3" to" n = 4 c. Find the wavelength of radiation to remove the electron from the second bohr orbit to infinity d. Find the kinetic energy potential energy and angular momentum of the electron in the first orbit Find the ionination energy of above electron system in electronvalt.

You can remove iron filings from sand by magnetic separation method. This method can be applied only when

You are provided with a mixture containing sand, iron filings, ammonium chloride and sodium chloride. Describe the procedures you would use to separate these constituents from the mixture?

(i) A regular polygon has 2016 sides and r is the radius of the circle circumscribing the polygon. Particles of equal mass are placed at 2015 vertices of the polygon. Find the distance of the centre of mass of the particle system from the centre of the polygon. (ii) In the last problem you have been asked to remove any one particle from the system so that the centre of mass of the remaining 2014 particles lies farthest from the geometrical centre of the polygon. Which particle will you remove ?
