When permanent magnets of a motor are replaced with more powerful ones, the motor rotation will increase. This is because there is more electricity being generated.

Given positive integer numInsects, write a while loop that prints that number doubled without reaching 200. Follow each number w
Gre4nikov [31]

Answer:

numInsects = 16

while numInsects < 200:

   print(str(numInsects) + " ", end="")

   numInsects *= 2

Explanation:

*The code is in Python.

Set the numInsects as 16

Create a while loop that iterates while numInsects is smaller than 200. Inside the loop, print the value of numInsects followed by a space. Then, multiply the numInsects by 2.

Given two integers as user inputs that represent the number of drinks to buy and the number of bottles to restock, create a Vend
ivann1987 [24]

Answer:

In C++:

#include <iostream>

using namespace std;

class VendingMachine {

 public:

   int initial = 20;};

int main() {

 VendingMachine myMachine;

   int purchase, restock;

   cout<<"Purchase: ";  cin>>purchase;

   cout<<"Restock: ";  cin>>restock;

   myMachine.initial-=(purchase-restock);

   cout << "Inventory: "<<myMachine.initial<<" bottles";  

   return 0;}

Explanation:

This question is incomplete, as the original source file is not given; so, I write another from scratch.

This creates the VendingMachine class

class VendingMachine {

This represents the access specifier

 public:

This initializes the inventory to 20

   int initial = 20;};

The main begins here

int main() {

This creates the object of the VendingMachine class

 VendingMachine myMachine;

This declares the purchase and the restock

   int purchase, restock;

This gets input for purchase

   cout<<"Purchase: ";  cin>>purchase;

This gets input for restock

   cout<<"Restock: ";  cin>>restock;

This calculates the new inventory

   myMachine.initial-=(purchase-restock);

This prints the new inventory

   cout << "Inventory: "<<myMachine.initial<<" bottles";  

   return 0;}

Suppose that the data mining task is to cluster points (with (x, y) representing location) into three clusters, where the points
solong [7]

Answer:

Explanation:

K- is the working procedure:

It takes n no. of predefined cluster as input and data points.

It also randomly initiate n centers of the clusters.

In this case the initial centers are given.

Steps you can follow

Step 1. Find distance of each data points from each centers.

Step 2. Assign each data point to the cluster with whose center is nearest to this data point.

Step 3. After assigning all data points calculate center of the cluster by taking mean of data points in cluster.

repeat above steps until the center in previous iteration and next iteration become same.

A1(4,8), A2(2, 4), A3(1, 7), B1(5, 4), B2(5,7), B3(6, 6), C1(3, 7), C2(7,8)

Centers are X1=A1, X2=B1, X3=C1

A1 will be assigned to cluster1, B1 will be assigned to cluster2 ,C1 will be assigned to cluster3.

Go through the attachment for the solution.

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:

<em>cout<<compute_gas_volume(P,T,n);</em>

<em />

<em>Where P, T and n are double variables and they must have been initialized</em>
