A rear wheel drive car of mass 1000 kg is accelerating with a constant acceleration without slipping from 0 to 60 m/s in 1 min.

What will be friction force acting on each rear wheel of the car? 1000 N 60000 N 30000 N 500 N

Answer:The force that acts on the wheels equals 1000 Newtons

Explanation:

We know acceleration is defined as

a=\frac{\Delta v}{\Delta t}=\frac{v_{2}-v_{1}}{t_{2}-t_{1}}\\\\\therefore a=\frac{60-0}{60-0}=1m/s^{2}

Now using newton's second law we have

F_{ext}=m\times a\\\\\therefore F_{ext}=1000\times 1=1000N

blsea [12.9K]

Answer:

The solution code is written in Java.

  1. public class Movie {
  2.    private double  [][] seats = new double[5][5];
  3.    private double totalSales;
  4.    public Movie(){
  5.        for(int i= 0; i < this.seats.length; i++){
  6.            for(int j = 0; j < this.seats[i].length; j++){
  7.                this.seats[i][j] = 12;
  8.            }
  9.        }
  10.        this.totalSales = 0;
  11.    }
  12.    public boolean bookSeat(int i, int j)
  13.    {
  14.        if(this.seats[i][j] != 0){
  15.            this.totalSales += this.seats[i][j];
  16.            this.seats[i][j] = 0;
  17.            return true;
  18.        }else{
  19.            return false;
  20.        }
  21.    }
  22. }

Explanation:

The method, bookSeat(), as required by the question is presented from Line 16 - 26 as part of the public method in a class <em>Movie</em>.  This method take row,<em> i</em>, and column,<em> j</em>, as input.

By presuming the seats is an two-dimensional array with all its elements are  initialized 12 (Line 7 - 10). This means we presume the movie ticket price for all the seats are $12, for simplicity.

When the<em> bookSeat() </em>method is invoked, it will check if the current price of seats at row-i and column-i is 0. If not, the current price, will be added to the <em>totalSales </em>(Line 19)<em> </em>and then set the price to 0 (Line 20) and return <em>true</em> since the ticket is successfully sold (Line 21).  If it has already been sold, return <em>false</em> (Line 23).

suter [353]

Answer:

total_cost = cost + tax

Explanation:

Step1) Let the 2 variable for take input from user e.g price and quantity

var price ;

var quantity ;

var cost ;

var tax ;

var total_cost ;

Step2) take input from user quantity of item 'A'

step3) cost = price * quantity

Step4) tax = 0.08 * cost

Step5) total_cost = cost + tax

Step6) print the total_cost

Water from an upper tank is drained into a lower tank through a 5 cm diameter iron pipe with roughness 2 mm. The entrance to the
nignag [31]

Answer:

Relative roughness = 0.04

Explanation:

Given that:

Diameter = 5 cm

roughness = 2 mm

At inlet:

Minor coefficient loss k_{L1} = 0.4

At exit:

Minor coefficient loss k_{L2} = 1

Height h = 4m

Length = 5 m

To find the relative roughness:

Relative roughness is a term that is used to describe the set of irregularities that exist inside commercial pipes that transport fluids. The relative roughness can be evaluated by knowing the diameter of the pipe made with the absolute roughness in question. If we denote the absolute roughness as e and the diameter as D, the relative roughness is expressed as:

e_r = \dfrac{e}{D}

e_r = \dfrac{0.2 }{5}

\mathbf{e_r = 0.04}
