Antitrust laws are used to theoretically protect consumers from businesses that seek to distort the market through unfair practices. Antitrust laws prevent the creation of cartels or groups of companies that work in conjunction to raise the costs of goods above the market value that would occur with competition. The also restrict the mergers and acquisitions of companies that would restrict or inhibit competition if a company were to get too large. And finally these laws prevent the misuse or creation of monopoly power by a single or a few large firms to distort the market and prevent competition and pricing that is deemed to be a fair market price to consumers.

Answer:
(a) E=λ/(2\pi e0 r)
(b) E = 0
Explanation:
(a) We can use the Gaussian's Law to calculate the electric field at any distance r from the axis. By using a cylindrical Gaussian surface we have:
where λ is the total charge per unit length inside the Gaussian surface. In this case we have that the Electric field vector is perpendicular to the r vector. Hence:
(b) outside of the outer cylinder there is no net charge inside the Gaussian surface, because charge of the inner radius cancel out with the inner surface of the cylindrical conductor.
Hence, we have that E is zero.
hope this helps!!
Explanation:
Density is mass divided by volume:
D = M / V
Given V = 79000 cm³ and D = 13.6 g/cm³:
13.6 g/cm³ = M / (79000 cm³)
M = 1,074,400 g
M = 1,074 kg
Round as needed.
