A copper ball with a radius of 1.5 cm is heated until its diameter has increased by 0.20 mm. Assuming a room temperature of 22°C, find the final temperature of the ball.

(a) An arteriole has a diameter of 0.029 mm and carries blood at the rate of 6.2 10-6 cm^3/s. What is the speed of the blood in the arteriole? (b) Suppose the arteriole branches into 340 capillaries, each with a diameter of 4.0 10-6 m. What is the blood speed in the capillaries? (The low...
