What are possible units for impulse? Check all that apply. kg • m kg • N • s N • m

Vlada [557]

We know that impulse is simply the product of Force and time:

Impulse = Force * time

Since Force has a unit of Newton or kg m/s^2 and time is in seconds, therefore impulse can have units as:

N s

What characteristics of EM waves did you discover?

jarptica [38.1K]

The characteristics of electromagnetic waves typically represent as follows:

There are changes in the electric and magnetic fields simultaneously so that both fields have maximum and minimum values at the same time and place.
The direction of the electric field and the magnetic field are perpendicular to each other. The direction of both is perpendicular to the direction of the wave propagation.
The shape of electromagnetic waves is transverse waves.
It has general wave characteristics like polarization, reflection, refraction, interference, and diffraction.
The amount of the electric field (E) is directly proportional to the magnitude of the magnetic field, with the relationship E = cB.
The universal constant of the velocity of electromagnetic waves in a vacuum is $\boxed{ \ c = 3 \times 10^8 \ m/s. \ }$
The speed at which electromagnetic waves propagate depends merely on the electrical and magnetic properties of the medium that it travels on.
Because electromagnetic waves do not contain an electric charge, they do not experience any possible deviation in the electric or magnetic fields.

<h3>Further explanation</h3>

Two physicists who contributed significantly to developing the concept of electromagnetic waves are Faraday and Maxwell around 1831-1864.
From the observations, Faraday suggested that changes in the magnetic field cause an electric charge to flow in the loop of wire, contributing in the emergence of an electric field.
Maxwell proposed a reverse process, which is a change in the electric field will generate a magnetic field.
As follows, according to Faraday's Law, changes in sinusoidal magnetic fields generate electric fields which also change sinusoidally.
Meantime, according to Maxwell's Hypothesis, changes in sinusoidal electric fields generate magnetic fields which also change sinusoidally.
Furthermore, there is a process of combining electric and magnetic fields that propagate in all directions called electromagnetic waves.

starting at a position of 0 m, if the man is moving at a constant velocity of 2 m/s, it will take seconds for him to reach a pos

Harman [31]

The calculated time is 6 seconds.

Time is defined by physicists as the flow of events from the past through the present and into the future. In essence, a system is timeless if it is unchanging. When describing events that take place in three-dimensional space, time can be thought of as the fourth dimension of reality. Even if time isn't directly connected to energy, it is undoubtedly connected to many other components of energy. For instance, the movement of energy across the universe can affect the direction of time (from the past to the future).

V= 2 m/s

d=12 m

t=?

we know that velocity=displacement / time

time= displacement / velocity

= 12/2

=6 seconds

the calculated time is 6 seconds.

Your body uses the process called MITOSIS to make new, identical cells to replace those that are lost or damaged.

Mitosis is a type of cell division that occurs in somatic cells or body cells. The purpose of mitosis is to make diploid cells or copies of the same cell. They are identical daughter cells, which are also identical to its parent cell.

Interphase is the first step to cell division. It is the longest stage in the cell division cycle. It is at this time where the cell prepares itself for division. At this point, the cell is copying the DNA strand of a chromosome it is meant to produce. The cell grows and stores energy, and at the same time, it starts to replicate the organelles of the cell it will produce.

Describe the four steps of mitosis:

Prophase: The nuclear envelope breaks down at this stage and the centriole divides into two. Each centriole will go to the opposite sides of the cell and start to form spindle. You can see the chromosomes under a light microscope and you will see them assume the X-shape. The X-shape are two sister chromatids that are joined at the middle.

Metaphase: It is at this stage where the chromosomes line up along the middle of the cell. Spindles start to attach to the centromere of the lined-up chromosomes, preparing to split them.

Anaphase: Chromosomes start to split up at the centromere. The sister chromatids are pulled apart and brought to the opposite ends of the cell. The chromatids then become separate chromosomes. As the spindle fibers pull on the chromatids, they shorten. The chromatids form a V-shape.

Telophase: The nuclei start to form for each cell. At this point, you can no longer see the chromosomes because they are enveloped already within the nucleus.

Cytokinesis occurs at the end of cell division. It is the physical division of the cells, as they separate into two different cells. The cytoplasm splits into two, organelles distributed and the nucleus of each new cell is already distinct.

Parent cells are the cells that go through cell division to produce daughter cells. The information or the genetic material that make up the parent cell will be passed on to the daughter cells. In mitosis, the daughter cells will be identical to the parent cells, whilst in meiosis, the daughter cells will get its information or traits from both mother and father.

Gametes are sex cells. These are mature haploid germ cells (male or female) which unite with the opposite sex through sexual reproduction. This union forms a zygote. The male gamete is more commonly known as sperm cells, while the female gamete are called egg cells.

A HAPLOID is a cell containing two complete sets of chromosomes, one from each parent.

MEIOSIS divides a cell into four new daughter cells, each with half as many chromosomes as the parent cell.

Why does meiosis allow for the creation of organisms with unique characteristics?

Cell division though meiosis creates unique characteristics in an organism because unlike in mitosis, the daughter cells produced are not identical to the parent cell or each other. The chromosomes formed in meiosis have parts that are from the father and the mother, which also carry the traits of each. This brings out the unique characteristics of the off-spring.

Describe each step of meiosis:

Meiosis I: Chromosomes are copied at this phase. They condensed into more compact forms, similar to mitosis. The difference is that instead of the chromosomes lined up in single file, the chromosomes line up two-by-two. Now each group is called homologous chromosomes. These homologous chromosomes are what separate, each carrying a pair from the father and the mother cell.

Meiosis II:

In meiosis II, the process is similar to mitosis. It splits the already divided cells further into four cells. The result is that each gamete will have two monovalent chromosomes. These cells are not identical to the parent cell. They have part of each parent cell.

Haploid cell refers to a cell that has half the number of chromosome as its parent cell. For example, if a parent cell starts with 46 chromosomes, the haploid cells have only 23 chromosomes.

Both Meiosis and Mitosis are a type of cell division that occurs in eukaryotic cells. They produce daughter cells. Those are mainly the similarities of the two. As for the differences between the two, there are several that can be pointed out.

In Mitosis, the number of daughter cells made is 2 and they are identical. These daughter cells are called diploid. They go through only 1 nuclear division and it occurs in somatic cells. The main function of mitosis for growth and asexual reproduction.

In Meiosis, the number of daughter cells made is 4 and they are not identical. These daughter cells are called haploid. They go through 2 nuclear divisions and they occur in the gonads. The main function of meiosis is to produce sex cells.
