Answer:

Explanation:

We know that Drag forceF_D

  F_D=\dfrac{1}{2}C_D\rho AV^2

Where

             C_D is the drag force constant.

                 A is the projected area.

                V is the velocity.

                ρ is the density of fluid.

Form the above expression of drag force we can say that drag force depends on the area .So We should need to take care of correct are before finding drag force on body.

Example:

 When we place our hand out of the window in a moving car ,we feel a force in the opposite direction and feel like some one trying to pull our hand .This pulling force is nothing but it is drag force.

anyanavicka [17]
<h2>Symptom of Pneumatic Governor System</h2>

Explanation:

  • Engine speed will rise is right answer
  • Pneumatic Governor system that utilizations power from moving air delivered by pivoting flywheel blades to detect engine speed
  • Electronic Governor System Uses a limited point torque engine in place of the governor spring and -speed-sensing device utilized in a mechanical governor system
  • A governor is a system that is utilized to keep up the mean speed of a engine, inside specific cutoff points, under fluctuating burden conditions
  • It does this by managing and controlling the measure of fuel provided to the motor
  • Governors are likewise fitted in assistant diesel motors or generators, and alternators on the ship

The meter is connected to perform a diagnostic check. Which type of fault can be isolated using the meter when connected as show
IgorC [24]

The type of fault which can be isolated using the meter when connected in what is shown in the experiment is shorting to ground in the load and is therefore denoted as option B.

<h3>What is Load?</h3>

This is referred to as an electrical component which consumes power and examples include bulb,resistor etc. They also form part of a circuit which is the path in which electric current flows.

A short circuit to ground means that the load will turn and stay on as long as there is power in the circuit thereby resulting in the fuse being blown. This is because the fuse offers some form of protection to the circuit thereby resulting in different forms of damage experienced in this type of scenario.

Write a short summary of the power of dreams
slava [35]

Answer:

The Power of a Dream

You don’t just think a dream. You feel it in your bones and in your heart.

Via Your Road Map for Success:

“I believe that each of us has a dream placed in the heart. I’m not talking about wanting to win the lottery. That kind of idea comes from a desire to escape our present circumstances, not to pursue a heartfelt dream. I’m talking about a vision deep inside that speaks to the very soul. It’s the thing we were born to do. It draws on our talents and gifts. It appeals to our highest ideals. It sparks our feelings of destiny. It is inseparably linked to our purpose in life. The dream starts us on the success journey.”

A Dream Gives Us Direction

Our dreams act as a compass and help us choose a path, among our many options. Dreams shape our choices that shape our way forward.

A Dream Helps Us Prioritize

Dreams help us weight our choices and make trade-offs based on what we truly value, and what really matters to us.

Via Your Road Map for Success:

“A dream gives us hope for the future, and it also brings us power in the present. It makes it possible for us to prioritize everything we do. A person who has a dream knows what he is willing to give up in order to go up. He is able to measure everything he does according to whether or not it contributes to the dream, concentrating his attention on the things that bring him closer to it and giving less attention to everything that doesn’t.”

A Dream Adds Value to Our Work

The same job takes on new meaning when we add emotion and add vision and bring our dreams to life.

Via Your Road Map for Success:

“A dream puts everything we do into perspective. Even the tasks that aren’t exciting or immediately rewarding take on added value when we know they ultimately contribute to the fulfillment of a dream. each activity becomes an important piece in that bigger picture.

It reminds me of the story of a reporter who talked to three construction workers pouring concrete at a building site, ‘What are you doing?’ he asked the first worker, ‘I’m earning a paycheck he grumbled.’

The reporter asked the same question of a second laborer, who looked over his shoulder and said, ‘What’s it look like I’m doing? I’m pouring concrete.’

Then he noticed a third man who was smiling and whistling as he worked. ‘What are you doing/’ he asked the third worker.

He stopped what he was doing and said excitedly, ‘I’m building a shelter for the homeless.‘ He wiped his hands clean on a rag and then pointed, ‘Look, over there is where the kitchen will be. And that over there is the women’s dormitory. This here …’

A Dream Predicts Our Future

We create our future by chasing our dreams, and it’s what we become in the pursuit of our dreams, that makes the journey worth it.

Dare to Act on Your Dreams

Don’t let your dreams sit on the shelf. Live them. Breathe them. Be that change you always wanted.

What is Potential flow?
nordsb [41]

Answer: Potential flow states about the velocity field considering it as gradient of scalar function such as the velocity potential. It is considered same as irrotational flow.

Explanation:In the study of fluid dynamics , potential flow is stated as the term for describing about the velocity field taking it as the gradient of a scalar function. Therefore, potential flow is stated by an irrotational velocity field  and there is a irrotation because of the curl of the gradient of scalar quantity is zero.Potential flow is considered same as the irrotational flow that is the particles in the fluids that do not rotate.
