Question Topic 5: Endocrine Case Study

Following routine blood work your doctor informs you that you have primary hyperthyroidism. Based on this diagnosis answer the following questions•What is the difference between primary and secondary hyperthyroidism•Would you expect the blood work to show elevated or decreased levels of thyroid hormone (thyroxine; T3/T4) and thyroid stimulating hormone (TSH)? Why?•If left untreated, would you expect a goiter to develop? Why?

## A nonconducting rod of length L has charge -q uniformly distributed

Question A nonconducting rod of length L has charge -q uniformly distributed along its length. (a) What is the linear charge density of the rod? (b) What is the electric field at point P, a distance a from the end of the rod? (c) If P were very far from the rod compared to L, the rod would look like a point charge. Show that your answer to (b) reduces to the electric field of a point charge for a

## 1. For a top player, a tennis ball may leave the racket on the serve

Question 1. For a top player, a tennis ball may leave the racket on the serve with a speed of 55 m/s (about 120 mi/h). If the ball has a mass of 0.060 kg and is in contact with the racket for about 4 ms (4 x 10-3 sec.), estimate the average force on the ball. 2. A 10,000 kg railroad car A, traveling at a speed of 24.0 m/s strikes an identical car, B, at rest. If the cars lock together as a result of the collision, what is their common speed just afterward? 3. A 1 kg ball moving at 12 m/s collides head-on with a 2 kg ball moving in the opposite direction at 24 m/s. Determine the motion of each after impact of (a) e = 2/3, (b) the balls stick together, and (c) the collision is perfectly elastic. 4. A 40,000 kg truck car is coasting at a speed of 5 m/s along straight track when it strikes a 30,000 kg stationary truck and couples it. What will be their combined speed after impact?

## 1. A 1.60 m long steel piano wire has a diameter of 0.20 cm. How great

Question 1. A 1.60 m long steel piano wire has a diameter of 0.20 cm. How great is the tension in the wire if it stretches 0.25 cm when tightened? 2. A load of 50 kg is applied to the lower end of a steel rod 80 cm long and 0.6 cm in diameter. How much will the rod stretch? Y = 190 GPa for steel. 3. An iron rod 4 m long and 0.5 cm2 in cross-section stretches 1 mm when a mass of 225 kg is hung from its lower end. Compute Young’s modulus for the iron.
