Which of the following is true about structures derived from the epidermis? 

Dynamic pricing is a by-product of digital personalization.

What are the different versions of CT scanners called historically?

Which of the following is true regarding sensory neurons?

Steam at atmospheric pressure is being condensed in an air-coupled heat exchanger containing 500 fins. The assembly is 1 m long and 0.2 m deep, and the air channels are 20 mm wide. The fins are made of aluminum (k = 200 W/m-K) and are 0.1 mm thick. The air temperature is at 25oC, with a heat transfer coefficient of 35 W/m2-K.  Assume that the exterior of the assembly is fully insulated. a) Calculate the minimum temperature of the aluminum fin and determine its location. b) How much heat do all the fins transfer? c) How much heat does the entire assembly (fins and tube walls) transfer? d) How much heat would the entire assembly transfer if the fins were perfect?                                                                               (20 min, 30 points)  

Which of the following is true about synovial joints?   

A cylindrical water heating element consists of an inner rod (k = 2 W/m-K, r = 6 mm) that produces heat, surrounded by a protective sheath of outer radius 9 mm and k = 25 W/m-K.  There is no gap between the rod and the sheath.  The outer surface temperature of the sheath is 500 K, and the water being heated is at 300 K, with h = 2000 W/m2-K.  Calculate: a) The temperature at the inner surface of the sheath b) The temperature at the center of the heating element.                        (25 min, 35 points)    

All of the following are true regarding somatosensation except: 

What prints when the following code executes? Give an exact output.   int x = 15;boolean output = x – x/5 > 12;System.out.print(output);

Write a set of instructions that does the following: First prompt the user for input for a number between 10 and 20 (inclusive), then validate that the user actually entered a number between 10 and 20 (inclusive).    If the user did not provide a valid entry, then the code continues to prompt the user and read the input.   When a valid input is entered, print the value to the screen.   (Note: Do not use break, System.exit(), or continue. Write only the code that would appear in the main method. You may assume any necessary import statements are included.)
