Consider the following program written in C syntax:

void swap (int a, int b) {
int temp;
temp = a;
a = b;
b = temp;
}
void main () {
int value = 2, list [5] = {1, 3, 5, 7, 9};
swap (value, list [0]);
swap (list[0], list[1]);
swap(value, list[value]);

for each of the following parameter-passing methods, what areall of the values of the variables value and list after each of thethree calls to swap?

a. Passed by value
b. Passed by reference
c. Passed by value-result

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?
