There are five distinct types of fire extinguishers, each identifiable by specific color codes.

Red - Water-based

Creme - Foam-based

Blue - Powder-based

Black - CO2 or carbon dioxide-based

Yellow - Wet chemical-based

The type of fire extinguisher required is determined by the class of fire being dealt with.

Class A - Combustible materials (e.g., paper, wood) Recommended extinguishers - Red, Creme, Blue, and Yellow. (Avoid using Black)

Class B - Flammable liquids (e.g., paint, petrol, alcohol) Recommended extinguishers - Creme, Blue, and Black. (Avoid using Red or Yellow)

Class C - Flammable gases (e.g., butane, methane) Recommended extinguishers - Blue (Avoid using Red, Creme, Black, or Yellow)

Class D - Flammable metals (e.g., lithium, potassium) Recommended extinguishers - Blue (Avoid using Red, Creme, Black, or Yellow)

Class F - Deep fat fryers (e.g., chip pans) Recommended extinguishers - Yellow (Avoid using Red, Creme, Blue, or Black)

Electrical - any kind of electrical device

(e.g., computers, generators) Recommended extinguishers - Blue and Black (Avoid using Red, Creme, or Yellow)

Answer:

153.2 J

Explanation:

Let’s first identify our known variables:

mass (m) of the block = 10 kg

distance slid down (i.e., displacement) = 2 m

coefficient of kinetic friction (μk) = 0.2

In the following diagram, if we analyze the force component directed along the displacement, we find

Fcos 40°

100 (cos 40°)

76.60 N

The work done by the frictional force is then calculated as:

W = × displacement

W = 76.60 × 2

W = 153.2 J

Therefore, the work done by the frictional force equals 153.2 J

Answer:

The following includes the explanation, code, and resulting outputs.

C++ Code:

#include <iostream>

using namespace std;

int main()

{

int year;

cout<<"Enter the car model year."<<endl;

cin>>year;

if (year<=1969)

{

cout<<"Few safety features."<<endl;

}

else if (year>=1970 && year<1989)

{

cout<<"Probably has seat belts."<<endl;

}

else if (year>=1990 && year<1999)

{

cout<<"Probably has antilock brakes."<<endl;

}

else if (year>=2000)

{

cout<<"Probably has airbags."<<endl;

}

return 0;

}

Explanation:

The challenge involved displaying feature messages for a car based on its model year.

Logical conditions were integrated into the coding. The implementation has been verified with multiple inputs producing the expected results.

Output:

Enter the car model year.

1961

Few safety features.

Enter the car model year.

1975

Probably has seat belts.

Enter the car model year.

1994

Probably has antilock brakes.

Enter the car model year.

2005

Probably has airbags.

Answer:

90 L.atm

Explanation:

According to the provided details:

First pathway:

A( 3 atm, 20 L) → C ( 1 atm, 20 L) → D (1 atm, 50 L)

Second pathway:

A(3 atm, 20 L) → B( 3 atm, 50 L) → D ( 1 atm, 50 L)

As the number of moles is 1.00 moles

To calculate wAB;

A → B signifies the transformation is happening at a steady pressure;

Thus,

wAB = pressure multiplied by the change in volume

wAB = P(V₂ - V₁)

wAB = 3 atm (50 L - 20 L)

wAB = 3 atm (30 L)

wAB = 90 L.atm

Answer:

The change in entropy of the steam is 2.673 kJ/K

Explanation:

The mass of the liquid-vapor mixture is 1.5 kg

The mass in the liquid phase is calculated as 3/4 × 1.5 kg = 1.125 kg

The mass in the vapor phase is calculated as 1.5 - 1.125 = 0.375 kg

According to the steam tables

At a pressure of 200 kPa (200/100 = 2 bar), the specific entropy of steam is found to be 7.127 kJ/kgK

The entropy of steam can be calculated as specific entropy multiplied by mass = 7.127 × 0.375 = 2.673 kJ/K
