The figure shows a point charge +q outside a hollow conductor and a point charge +2q in a cavity in the conductor. Points A, B, C, and D are simply points in space, not point charges. Point B is on the outside surface of the conductor. Which of the statements below are correct once electrostatic equilibrium is reached? Select all that apply.

A primary characteristic of the genetic map is that it must include branches to show alternative relationships between markers.

When narrow-sense heritability is high for a particular trait, offspring tend to resemble their parents for that trait.

The total number of alleles used in calculating allelic frequencies is equal to the total number of individuals (N), assuming a diploid species.

Both autosomal recessive and dominant traits appear equally in males or females.

Major goals of mechanical ventilation include to: ensure adequate tissue oxygenation restore and maintain acid-base balance reduce the work of breathing provide adequate alveolar ventilation

Loads P = 425 N and Q = 900 N act on an oak beam. Determine the magnitude of the largest shear force (consider both positive and negative values) in the beam. Let a = 0.6 m and b = 1.4 m.

A solid constant-diameter shaft is subjected to the torques shown. The bearings shown allow the shaft to turn freely. Determine the internal torque in segment (2) of the shaft. Assume that TA = 240 N·m, TB = 605 N·m, TC = 755 N·m, and TD = 390 N·m.

A tubular steel [G = 80 GPa] shaft with an outside diameter of D = 90 mm and a wall thickness of t = 8 mm must not twist more than 0.05 rad in a 8-m length. Determine the maximum power that the shaft can transmit at 542 rpm.

A compound steel [G = 80 GPa] shaft consists of solid 30-mm-diameter segments (1) and (3) and tube segment (2), which has an outside diameter of 52 mm and an inside diameter of 44 mm. Determine the maximum shear stress in tube segment (2).
