The number of particles crossing a unit area perpendicular to the x-axis in a unit time is given by n = -D (n2-n1), where n1 and n2 are the numbers of particles per unit volume The number of particles crossing a unit area perpendicular to the x-axis in a unit time is given by n [...]

The relative density of a material of a body is found by weighing it first in air and then in water. If the weight of the body in air is W1 = 8.00 +- 0.05 N and the weight in water is W2 = 6.00 +- 0.05 N, then the relative density and t is [...]
