Plot a graph showing variation of activity of a given radioactive sample with time.

Sketch of a graph showing variation of resistivity of carbon with temperature?

Plot a graph showing variation of de-Broglie wavelength (lambda) associated with a charged particle of mass m, versus 1/sqrtV , where particle is accelerated. How does this graph give us the information regarding the magnitude of the charge of the particle?
