(ii) The student obtained a value of 0.16 ms l for the terminal velocity of the sphere.
Calculate the viscosity n of the washing up liquid in Pas.
radius of sphere = 4.8 x 10-3
weight of sphere = 3.5 x 10
density of washing up liquid

What are the factors that affect the resistance of a wire?

Emagnitude of the electrical force acting between a +2.4 ×  10–8  c charge and a +1.8 ×  10–6  c charge that are separated by 0.008 m is    n, rounded to the tenths place.

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
