Using E = mc2, we found that 1 kg of mass has the energy equivalent of 20 megatons. Estimate how many megatons of energy would be required to accelerate a spaceship with a mass of one million kg to a speed of 0.99c. What does this suggest to you regarding the practicality of space travel at relativistic speeds?

A particle is found to carry the kinetic energy, K=(γ−1)mc2, which is equal to the energy of a photon. If the speed of the particle is v=0.500c, find the ratio of the wavelength of the photon to the de Broglie wavelength of the particle.

1. Two firms can reduce pollution at the following marginal abatement costs: MC1 = 12Q1 MC2 = 4Q2 where Qi is the abatement (pollution control) of firm i = 1, 2. In the absence of regulation, each firm would emit 40 units of emissions. Assume that each firm’s objective is to minimize its compliance costs (c) The aggregate marginal cost function for this two-firm industry is: MC = 3Q Suppose the marginal benefit of pollution control is given by: MB...

Suppose Standard OIl consists of two firms with marginal costs MC1(Q1) = 6+Q1 and MC2(Q2) = 6+2Q2. The inverse demand function would be P(Q) = 194-2Q, where Q=Q1+Q2 Suppose that standard oil is a dominant firm with a competitive fringe given by Qf(P)=-6+P/2. 1) How much oil will standard oil produce in the prescence of a competitive fringe 2) How much oil will the competitive fringe produce 3) What will be the market price for a barrel of oil? 4)...

Suppose that D and E are sets, and D ⊆ E. Let A = P(E). Recall that P(E) denotes the set of all subsets of E. Define a relation R on A by R = {(X, Y) ∈ A × A: [(X − Y) ∪ (Y − X)] ⊆ D}. So, XRY if and only if [(X−Y) ∪ (Y −X)] ⊆ D. Prove that R is an equivalence relation on A.
