Which quantities define momentum?
A. Mass and speed
B. Mass and velocity
C. Mass and acceleration
D. Mass and force

Answers

Momentum is the quantity of motion of a moving body. It is expressed mathematically as p = m * v and has units of kg m/s.

The quantities that significantly define the momentum are known as Mass and velocity. Thus, the correct option for this question is B.

What is Momentum?

Momentum may be defined as a type of physical property that remarkably describes the motion of any moving object. It is a type of vector quantity as it possesses both magnitude and direction. It may be generally characterized as the product of mass and velocity.

According to the context of this question, the momentum of any object may be calculated as follows:

Momentum, P = M × V, where M = mass of an object and v = velocity of an object.

The unit of momentum is Newton-second (N-s) or kg m/s.

Therefore, the quantities that significantly define the momentum are known as Mass and velocity. Thus, the correct option for this question is B.

Describe three other features of a bacterial cell.

Answers

Answer:

hope it helped

Explanation:

Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.

The features of a bacterial cell are the following:

Bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.

They are essential in the decomposition processes of organic matter, necessary for the recycling of elements such as carbon or nitrogen.

They reproduce quickly and by asexual procedures, which consist of the replication of the progenitor cell in two exactly equal to it (binary fission).

They are made up of a single cell without a cell nucleus, but with a nucleoid (an irregular region where the circular DNA of prokaryotes is found).

They have a peptidoglycan cell wall that covers the cell outside the plasma membrane.

Scattered throughout the bacterial cytoplasm are ribosomes (in which protein synthesis takes place) and there are also often plasmids (small non-chromosomal DNA molecules).

Some bacterial cell also have capsules, a rigid protective structure that is outside the cell wall and flagella to move (if they are mobile).

Therefore, we can conclude that bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.

What is the procedure of formation of Clastic sedimentary rocks?

Clastic sedimentary rocks are formed by the weathering process, In this process rocks get breakdown into sand, clay particles by the wind, water, and ice.

Clastic sedimentary rocks are also known as sandstone, and they are made of rocks and minerals. They are classified based upon composition, size, and texture.

Breccia is a clastic sedimentary rock with angular particles. Breccia is composed of particles that have diameter of greater than two millimeters. Breccia is formed by accumulation of angular broken rock or mineral debris. Breccia differ in composition according to the composition of mineral and rock from which the angular fragments were formed.

Answer:

direction of gravitational  pull of the Sun on the planet

Explanation:

A planet orbiting or revolving around the sun due to gravitational  force of the Sun on the planet which attracts the planet and compel the planets to move in a circular path. If this force of gravity is not applied on the planets, the planets will move in a straight line instead of circular direction so gravitational  pull of the Sun on the planet is very necessary for moving planets in a circular path.

What is one trait that could be used to separate these albatrosses into two groups of two birds each?

Answers

The correct answer to this open question is the following.

You did not attach the options for this question. However, we can answer the following.

Although there are no pictures of the Albatross, we can say that one trait that could be used to separate these albatrosses into two groups of two birds each is "a large group of solid black feathers vs. black and grey patterned feathers."

If someone ask you what are the birds with larger wings, you probably would answer "the Bald Eagle," Or any other kind of eagle. Maybe the Southamerican Condor. And those answers are incorrect. The correct answer: the Albatross.

This is a carnivore bird which wingspan varies from 6.5 to 11 to 11 feet, Its average weight is 22 pounds. These impressive birds can use their long wings to fly over the seas for miles and miles, without taking a rest.

A cave system is actually not one single cave but a series of connected caves. The Mammoth Cave in Kentucky is the longest cave system in the world. The system is remarkably stable because it is made of limestone that is covered by a layer of sandstone. There are more than 405 miles of passageways that weave through the massive cave system. Every year, new caves and connections are discovered.Several North American tribes have been known to settle in the cave system throughout history. Scientists have been researching the people that had once called the cave system home. The remains found in the cave had been protected from the elements, which makes them great specimens for studying. They are so well preserved that scientists can easily study the people's dietary habits. This research has found that the people living in the cave were once hunter-gatherers, and then they transitioned to a community with domestic plants and agriculture. That means they learned how to grow their own food instead of having to hunt for it.Researching in this type of environment is tricky business. Moving an artifact even a little can diminish its research value. That is why explorers are trained to not disturb artifacts they find. They learn how to collect and study the items they find without spoiling them. It is because of this sensitivity that the cave system is protected and is now a national park.Select the reason the author included the point that the remains found in the cave had been protected from the elements. aIt explains why people lived in the caves throughout history. bIt explains why researchers are trained to not disturb artifacts. cIt explains why the system is now a protected national park. dIt explains why they are great specimens for studying.
