Carmen is helping load furniture and boxes onto a moving truck. She picks up boxes of her things, places them on a cart, and pushes the cart to the moving van. Which term best describes the type of force Carmen uses?

Answer:

The correct answer is c. the truck driver.

Any object is said to be the motion if its relative distance with respect to a reference point is keep on changing.

For example, a kid travelling through a train might seem to be stationary with respect to the seat. However, he would seem to be moving if we see him in respect to the railway track outside the train.

A reference point is anything (place, person or any object) used to determine if something or someone is in motion.

In the given situation, the distance between truck driver and bulldozer will remain the same throughout the journey as it is being placed on the back of the truck. Hence, the correct answer is truck driver.

Which main-sequence on the Hertzsprung-Russell diagram are the least massive?
xxTIMURxx [149]

The Hertzsprung-Russell diagram is one of the most important tools in the study of stellar evolution. Developed independently in the early 1900's by Ejnar Hertzsprung and Henry Norris Russell, it plots the temperature of stars against their luminosity (the theoretical HR diagram), or the color of stars against their absolute magnitude

Depending on its initial mass, every star goes through specific evolutionary stages dictated by its internal structure and how it produces energy. Each of these stages corresponds to a change in the temperature and luminosity of the star, which can be seen to move to different regions on the HR diagram as it evolves. This reveals the true power of the HR diagram – astronomers can know a star’s internal structure and evolutionary stage simply by determining its position in the diagram.

The Hertzsprung-Russell diagram the various stages of stellar evolution. By far the most prominent feature is the main sequence (grey), which runs from the upper left (hot, luminous stars) to the bottom right (cool, faint stars) of the diagram. The giant branch and supergiant stars lie above the main sequence, and white dwarfs are found below it.

What two elements have the same number of energy level (shells)?
melomori [17]

Answer:

Elements that are found in the same horizontal row (belong to the same period) in the periodic table, e.g. Fluorine and Neon both have the same energy level of 2.

<em>Note: The question does not specify any two elements.</em>

Explanation:

The modern periodic table is organized into eight vertical columns known as groups and seven horizontal rows known as periods. The atomic number ( number of protons in the nucleus) of elements increases when moving across the periodic table from left to right. The horizontal rows or periods represents an energy levels or the number of electron shells in an element. Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. Elements belonging to the same period have the same number of energy level or shells. For example, the elements belonging to Period 2 include lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon. These all have the same number of energy level of 2.

What would be first three amino acids in the protein formed from this gene? UTC GTU TTG
Andrews [41]
<h2>Answer:</h2>

The three amino acid will be Tyrosine, Asparagine and Lysine respectively to sequence.

<h3>Explanation:</h3>

UTC GTU TTG

First the thymine in the sequence is changed to A, adenine because in the mRNA only three types of nucleotides are allowed which are Adenine, thymine and Uracil.

So the sequence will be:

UAC GAU AAG

These codons will be read by tRNA producing the polypeptide sequence of amino acids which are as follow:

Tyrosine Asparagine Lysine.
