Answer:

Technician A

Explanation:

Ohms law:  I= E/R so rest resistance must be present along with E/potential difference.  Even if just wire shorted together there is resistance but very little.

Tech B: Again ohms law.  Current flow is directly proportional to the voltage and inversely  proportional to R (resistance or impedance).

Which of the following is the LEAST-Likely cause of tire wear? A) Underinflation B) Braking C) Acceleration D) Tire rotation
mihalych1998 [28]

Answer:

Tire rotation is the least likely cause of tire wear. So, the option D is correct.

Explanation:

Step1

Under-inflation is the process of tire failure under low pressure. This contributes the wear on tire.

Step2

On breaking, kinetic energy changes to heat energy because of rubbing of tire. So, rubbing action increases the wear on the tire.

Step3

Acceleration on the vehicle increases the rubbing action as well as the wear and tear on the tire. So, acceleration is an also a major cause of tire wear.

Step4

Tire rotation has least amount of wear and tear due to no rubbing action.  It has less amount surface contact with the surface in rotation.  

Thus, tire rotation is the least likely cause of tire wear. So, the option D is correct.

Technician A says the final drive assembly always has a gear ratio of 1:1. Technician B says the final drive assembly provides f
Olenka [21]

Answer:

Technician B only is correct

Explanation:

The last stage of gears found between the vehicle transmission system and the wheels is the final drive ratio. The function of the final drive gear assembly is to enable a gear reduction control stage to reduce the rotation per minute and increase the wheel torque, such that the vehicle performance can be adjusted and the final gear ratio can be between 3:1 and 4.5:1 not 1:1

Therefore, technician B only is correct

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.
