Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10), print: 7 9 11 10 10 11 9 7 Hint: Use two for loops. Second loop starts with i courseGrades.length - 1. (Notes) Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array. See How to Use zyBooks". Also note: If the submitted code tries to access an invalid array element, such as courseGrades[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached, in which case the system doesn't print the test case that caused the reported message. 1 import java.util.Scanner; 2 3 public class CourseGrade Printer public static void main (String [] args) Scanner scnr = new Scanner (System.in); final int NUM_VALS 4 int courseGrades new int[NUM_VALS] int i 4 6 7 for (i 0; i < courseGrades.length; ++i) { courseGrades[il } 10 = Scnr.nextInt () 11 12 13 / Your solution goes here 14 15 16 } 17

The rear window of an automobile is defogged by attaching a thin, transparent, film-type heating element to its inner surface. By electrically heating this element, a uniform heat flux may be established at the inner surface. The interior air temperature and convection coefficient are 25 degrees C and 10 W/m2K and the exterior (ambient) air temperature and convection coefficient are -10 degrees C and 65 W/m2K. The window glass is 4mm thick, and the thermal conductivity of glass is 1. 4 W/mK. Find the electrical power that must be provided per unit window area to maintain an inner surface temperature of 15 degrees C using the resistance method

1) Estimate the stress the legs of a statistically-median, 82-kg man when standing. A typical adult human femur diameter is approximately 25 mm. Assume that the weight is distributed evenly between both legs (convert the data to psi). a) Repeat for a Holstein cow and a white-tailed deer. Assume the weight is distributed evenly between all legs. i) A Holstein cow weighs 1500 lbf and the leg has a diameter of 1.75 inches. i) The average weight of a female white-tailed deer is 150 lbf. The lower leg is comprised of the radius and the ulna, both of which have a diameter of 0.5 inches (focus on stress created in one of those bones so, divide the weight by 8) b) Assuming that the compressive strength of the bones in all three mammals is approximately equal, discuss the relative susceptibility to fractures. On a cello the 0.68 m long strings are tuned by winding one end around a peg. For a peg diameter of 15mm, calculate how many turns will be necessary to achieve a tension in the 1.36 mm diameter string of 160 N. Assume the string is made of solid music wire (look up the properties of this material). Show that the string is in the elastic region of the material behavior.

two players are playing a game where white or black pieces are represented by string, colors. the game rules are as follows: wendy moves first and then they take alternate turns. with each move, wendy may remove a white piece that has adjacent white pieces on both sides. likewise, with each move, bob may remove any black piece that has adjacent black pieces on both sides. after a piece is removed, the string is reduced in size by one piece. for instance, removing 'y' in 'xyz' results in 'xz'. when a player can no longer move, they have lost the game. determine who wins if wendy and bob both play with optimum skill
