Dimensional analysis for the plasma oscillation frequency: A plasma (hot. ionized gas. with lots of free electrons) of number density ne (number of free electrons per unit volume), can undergo periodic oscillations if disturbed. The relevant dimensional factors are e (the fundamental charge), m (the electron mass), the fundamental constant of electricity Co, and ne. Using dimensional analysis, find the oscillation frequency. *jp, in terms of those four quantities. That is, write omega_P alpha n_epsilon^alpha e^beta m^gamma e_0^delta and solve for alpha, beta, gamma, delta by matching dimensions. Recall that e_0 is defined from Coulombs law for the force between two charges, q_1, q_0 via. F_1,2 = q_1q_2/4 pi e_0 r^2

Which accounts for an increase in the temperature of a gas that is kept a constant volume

Newton's law of cooling states that the rate of change in the temperature t(t) of a body is proportional to the difference between the temperature of the medium m(t) and the temperature of the body. that is, startfraction dt over dt endfraction equals upper k left bracket upper m left parenthesis t right parenthesis minus upper t left parenthesis t right parenthesis right bracket , where k is a constant. let kequals0.04 left parenthesis min right parenthesis superscript negative 1 and the temperature of the medium be constant, m(t) font size decreased by 3 equivalent font size decreased by 3 294 kelvins. if the body is initially at 369 kelvins, use euler's method with hequals0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes.
