Answer:

The answer is Rotary Motion, I've taken the test

Explanation:

The bottom end of the piston is connected to a rod and crankshaft assembly. When the piston is forced downward in the cylinder, the piston’s downward motion is transferred to the rod and crankshaft. The rod and crankshaft then convert the up-and-down motion of the piston into rotary motion (circular motion).

This conversion of up-and-down motion to rotary motion can be compared to the motion produced by a regular bicycle. When you pedal a bike, the up-and-down motion of your feet on the pedals is converted into circular motion in the rear wheel. The same principle applies to an engine. The up-and-down motion of the piston is converted to circular motion in the crankshaft that can be used to power a piece of equipment.

C. Rotary Motion. Had this on my test just now so am sure its right!

Define a function compute_gas_volume that returns the volume of a gas given parameters pressure, temperature, and moles. Use

jeyben [28]

Question:

Define a function compute_gas_volume that returns the volume of a gas given parameters pressure, temperature, and moles. Use the gas equation PV = nRT, where P is pressure in Pascals, V is volume in cubic meters, n is number of moles, R is the gas constant 8.3144621 ( J / (mol*K)), and T is temperature in Kelvin.

Answer:

This solution is implemented in C++

double compute_gas_volume(double P, double T, double n){

double V = 8.3144621 * n * T/P;

return V;

}

Explanation:

This line defines the function, along with three parameters

double compute_gas_volume(double P, double T, double n){

This calculates the volume

double V = 8.3144621 * n * T/P;

This returns the calculated volume

return V;

}

To call the function from the main, use:

cout<<compute_gas_volume(P,T,n);

Where P, T and n are double variables and they must have been initialized

A method countDigits(int num) of class Digits returns the remainder when the input argument num(num > 0) is divided by the nu

sertanlavr [38]

Answer:

#include <iostream>

using namespace std;

class Digits

{

public:

int num;

int read() //method to read num from user

{

cout<<"Enter number(>0)\n";

cin>>num;

return num;

}

int digit_count(int num) //method to count number of digits of num

{

int count=0;

while(num>0) //loop till num>0

{

num/=10;

count++; //counter which counts number of digits

}

return count;

}

int countDigits(int num) //method to return remainder

{

int c=digit_count(num); //calls method inside method

return num%c;

}

};

int main()

{

Digits d; //object of class Digits is created

int number=d.read(); //num is read from user

cout<<"\nRemainder is : "<<d.countDigits(number); //used to find remainder

return 0;

}

Output :

Enter number(>0)

343

Remainder is : 1

Explanation:

As program is missing to find errors , a logically write program is written to find the remainder when a number is divided by its number of digits. A class Digits is constructed which has public variable num and methods read(), digit_count(), countDigits().

read() - This method reads value of num from the user and return num.
digit_count() - This method takes a integer as parameter and counts the number of digits of a number passed as argument. while loop is used to increement the counter until num<0. This returns the value of count.
countDigits() - This method takes a integer as a parameter and returns remainder when the argument is divided by number of digits of argument. Number of digits is calculated by using method digit_count().

At last in main method , object of Digits class is created and its methods are used to find the output.
