A train is moving in the positive direction down a track. First the train speeds up, and then it slows down. What is its acceler

tatuchka [14]

C.

The train first sped up, giving it a positive acceleration in the beginning. This eliminates D since that choice states that it begins with a negative acceleration. This also eliminates B since that choice states that the train only had a negation acceleration.

Next, the train slows down, giving it a negative acceleration. We’re looking for the answer choice that starts with a positive acceleration and ends with a negative one. This makes C the correct answer. Hope this helps!

The statement which describes how a machine can help make work easier is that It can put out more force than the input force by decreasing the distance over which force is applied, therefore the correct option is option A.

The total amount of energy transferred when a force is applied to move an object through some distance

The work done is the multiplication of applied force with displacement.

Work Done = Force * Displacement

As work done depends both on the force as well as the displacement force and be reduced by reducing the displacement if the same amount of work is performed by the machine.

The correct answer is option A since the statement that describes how a machine might assist in making work easier says that it can put out greater force than the input force by reducing the distance over which force is exerted.

katrin2010 [14]

According to Buckingham and Clifton, most business organizations are built on these two (2) flawed assumptions:

1. Everyone can learn almost everything.

2. People's best room for growth is in the areas of weakness.

Marcus W. Buckingham is an English author, business consultant and motivational speaker who was born on the 11th of January, 1966 in High Wycombe, Buckinghamshire, England.

Donald O. Clifton was an American author, educator, psychologist, business entrepreneur and researcher who was born on the 5th of February, 1924 in Butte, Nebraska‎, United States of America.

While studying as a student in Cambridge, Marcus W. Buckingham was recruited by Prof. Donald O. Clifton as an assistant in a research (survey) that was aimed at helping business organizations identify talents in various individuals, so as to effectively match them with the right job positions or roles.

In the book titled "Now, Discover Your Strengths" which was co-authored by both Buckingham and Clifton, most business organizations were said to be typically built on these two (2) flawed assumptions:

Everyone can learn to be competent in almost anything.

People's best (greatest) room for growth is in their areas of weakness.

However, the two (2) assumptions on which the world’s best managers operate include:

Each individual has an enduring and unique talent.

People's best (greatest) room for growth is in their areas of strength.
