Give a powerful way to determine an upper limit to the size of the electron.

Give the size of mitochondria.

Show the trajectory of a particle of different impact parameter and using it how did Rutherford determine the upper limit of the nuclear size ?

Give the limitations and uses of turbulence.

Give the equation to calculate energy of one electron.

Assertion: In parallel combination of electrical appliances, total power consum ption is equal to the sum of the powers of the indivisual appliances. Reason : Electrons move away from a region of lower potential to a region of higher potential.

An electron microscope uses electrons accelerated by a voltage of 50 kV. Determine the de Broglie wavelength associated with the electrons. If other factors (such as numerical aperture, etc.) are taken to be roughly the same, how does the resolving power of an electron microscope compare with that of an optical microscope which uses yellow light?

Which effect is developed commercially to determine the size and density of aerosol and other colloidal particles ?

For the following distribution, find the sum of the lower limit of the mediaan class and the upper limit of the modal class. {:("Class ",0-5,5-10,10-15,15-20,20-25),("Frequency "," "10," "15," "12," "20," "9):}
