After having done the hand calculation and pseudocode for a program that models inflating a spherical balloon, now implement the

task in Java. Remember, first the balloon is inflated to have a certain diameter (which is provided as an input). Then you inflate the balloon so that the diameter grows by an inch, and display the amount the volume has grown. Repeat that step: grow the diameter by another inch and show the growth of the volume.

Answer:

Explanation:

CODE :

import java.util.Scanner; // required imports for the class

class Balloon { // class to run the code

public static void main(String[] args) { // driver method

Scanner in = new Scanner(System.in); // scanner class to get the data

System.out.print("Diameter: "); // message

double diameter = in.nextDouble(); // prompt

double growth = 1; // local variables

int c = 0;

while (c < 10) { // iterate over the loop

double radius = diameter / 2; // calculate the radius

double vol = ((double)4 / 3) * 3.14 * radius * radius * radius; // calculate the initial volume

diameter = growth + diameter; // update the diamter

System.out.printf("\nIncrease in the Diameter is : %.0f", growth); // message

System.out.println("\nNew Diameter is : " + diameter); // print the diameter

radius = diameter / 2; // calculate the new diameter

double growthvol = ((double)4 / 3) * 3.14 * radius * radius * radius; // calculate the new volume

System.out.printf("Increase in the Volume is : %.0f", growthvol - vol); // message

System.out.println("\nNew Volume is : " + growthvol); // message

c++; // increment the count

}

}

}

Description :

During the casting or the calculation of the volume and the radius the RHS needs to be casted for the numerator with the double datatype so as to clearly get the result. And that the formula is also been updated.

Hope this is helpful.

Which test element is used to apply test execution settings for the main business flow excluding Login and Log out 1) Run time c

Svet_ta [14]

Test element is used to apply test execution settings for the main business flow excluding Login and Log out is "Transaction controller"

<u>Explanation:</u>

Transaction controllers are a technoscientifically kind of controllers that produce an additional sample that measures the overall time is taken or response time to perform its nested samplers.

The Controller has two checkboxes,those are

1.Generate Parent Samples

2. Include term of the timer and pre-post processors in the produced sample - It is the time which involves all processing samples within the Transaction controller, not just the HTTP samples. In Case one sample is lost or crashed then the entire Transaction Controller will fail. In case anyone sample assertion is failed then the complete Transaction Controller will fail.

The thrust F of a screw propeller is known to depend upon the diameter d,speed of advance \nu ,fluid density p, revolution per s

musickatia [10]

Answer:

<em>screw thrust = ML</em> $T^{-2}$ <em> </em>

Explanation:

thrust of a screw propeller is given by the equation = p $V^{2}$ $D^{2}$ x $\frac{ND}{V}$ Re

where,

D is diameter

V is the fluid velocity

p is the fluid density

N is the angular speed of the screw in revolution per second

Re is the Reynolds number which is equal to puD/μ

where p is the fluid density

u is the fluid velocity, and

μ is the fluid viscosity = kg/m.s = M $L^{-1}$ $T^{-1}$

<em>Reynolds number is dimensionless so it cancels out</em>

The dimensions of the variables are shown below in MLT

diameter is m = L

speed is in m/s = L $T^{-1}$

fluid density is in kg/ $m^{3}$ = M $L^{-3}$

N is in rad/s = L $L^{-1}$ $T^{-1}$ =

If we substitute these dimensions in their respective places in the equation, we get

thrust = M $L^{-3}$ $(LT^{-1}) ^{2}$ $L^{2}$ $\frac{T^{-1} L}{LT^{-1} }$

= M $L^{-3}$ $L^{2}$ $T^{-2}$

<em>screw thrust = ML</em> $T^{-2}$ <em> </em>

This is the dimension for a force which indicates that thrust is a type of force
