Answer:

In English traditional grammar, a phrasal verb is the combination of two or three words from different grammatical categories: a verb and a particle, such as an adverb or a preposition — to form a single semantic unit on a lexical or syntactic level. Examples: turn down, run into, sit up.

Answer:

.1 seconds per meter

Explanation:

I am going to assume they are asking for the average time per 1 meter.

Because it took 10.23 seconds to run 100 meters, we are going to divide 10.23 by 100. This number will be the time per 1 meter.

To divide by 100, we will move the decimal point over by two. That will give us .1023 seconds.

The question asks to round to the nearest tenth, so we round it to .1 seconds.

*Just some trivia: Danie van Blerk does in fact have a time of 10.23 seconds. He has the 1073rd best 100 meter dash time. First place, Usain Bolt, has a time of 9.58 seconds.

Answer:

Law of Inertia

Explanation:

That's its other name

Answer:

True.

Explanation:

The formula for the centripetal acceleration of an object can be calculated by the formula as follows :

[tex]a_c=\dfrac{v^2}{r}[/tex]

Where

v is the speed of an object

r is the radius of the circle

It means, the centripetal acceleration depends directly on the square of the object's speed and inversely on  the radius of the circle. Hence, the given statement is true.

Answer:

2nd bscause there is a reaction

Answer:

A, C

Explanation:

In order for a box to be moving at constant velocity, that means acceleration must be 0(as the speed isn't increasing). Thus, since F = ma, and a is 0, the net force must also be 0. The diagram must be completely balanced in every direction, which is why the two horizontal arrows must be equal values.

C is also true because gravity is a stronger force here than the applied force. We can calculate the force due to gravity with Fgravity = mg. Thus, we get the force as a result of gravity = 9.8*50, which is around 500N and much larger than the applied force of 200N.

Answer:

The fountain is 3.43 m high.

Explanation:

Circumference of the pool = 15 m.

C = 2[tex]\pi[/tex]r

where C is the circumference and r its radius.

r = [tex]\frac{C}{2\pi }[/tex]

 = [tex]\frac{15}{2(\frac{22}{7}) }[/tex]

r = 2.3864

radius of the pool = 2.40 m

So that the height of the fountain, h, can be determined by applying trigonometric function.

Tan θ = [tex]\frac{opposite}{adjacent}[/tex]

Tan 55 = [tex]\frac{h}{2.4}[/tex]

h = Tan 55 x 2.4

  = 1.4282 x 2.4

  = 3.4277

h = 3.43 m

The height of the fountain is 3.43 m.

Answer:

Anaphase

Explanation:

This is because the spindle fibres have shortened and is pulling the chromatids towards the poles of the cell. The chromatids have also separated.

The cell division which is shown in the picture is anaphase. The correct option is C.

Meiosis is divided into two main phases, each with its own set of subphases:

1 Meiosis I:

a. Prophase I: This is the longest and most complex phase of meiosis. During this phase, homologous chromosomes pair up and form bivalents, and crossing over occurs between the homologous chromosomes. The nuclear envelope breaks down, and spindle fibers form from the centrioles at opposite poles of the cell.

b. Metaphase I: During this phase, the homologous chromosomes line up along the metaphase plate, with one chromosome from each homologous pair facing each pole of the cell.

c. Anaphase I: During this phase, the spindle fibers contract and pull the homologous chromosomes towards opposite poles of the cell.

d. Telophase I: During this phase, the chromosomes reach the poles of the cell and the nuclear envelope reforms around each set of chromosomes. The cell then undergoes cytokinesis, resulting in two daughter cells.

2. Meiosis II:

a. Prophase II: During this phase, the nuclear envelope breaks down, and spindle fibers form from the centrioles at opposite poles of the cell.

b. Metaphase II: During this phase, the chromosomes line up along the metaphase plate, with sister chromatids facing opposite poles of the cell.

c. Anaphase II: During this phase, the spindle fibers contract and pull the sister chromatids towards opposite poles of the cell.

d. Telophase II: During this phase, the chromosomes reach the poles of the cell and the nuclear envelope reforms around each set of chromosomes. The cell then undergoes cytokinesis, resulting in four haploid daughter cells.

Meiosis involves two rounds of chromosome segregation, resulting in four haploid daughter cells that are genetically distinct from the parent cell.

Therefore, The correct option is C i.e anaphase.

Answer:

divided by 2 plus one entity_secured_pace_nun_box 9 divided by oee burned akward potion tri tour all around divided by 3 divided by 4

Explanation:

So the first few words in this statement talks about two and four being equal to around three therefore giving you "divided by 2" as you need to divide the four by 2 and add one to get 3. The next statement "the espn by the Xbox 360", espn can be deemed as a secured entity that paces around a nun therefore giving you entity_secured_pace_nun and since this is being multiplied by a box and by 360, you apply the "Improve Rule of Baseless Base". This rule allows you to get entity_secured_pace_nun_box_9. Box comes from multiplying what we have with box and the 9 comes from adding 3+6+0. Since a logical fire is present in this equation, you burn the letters in "two three" that have no protection, these letters are t,w,t,h, and r. Next, you can take cohedron that sounds like couldron and brew yourself an akward potion with the tri sided isosceles. The diameter can be seen as a round up rule that allows you to regroup the answer you have so far. The "by the three by four" can easily be translate from the "Baseless Base Rule Compilation" giving you divided by 3 and divided by 4. That is why the answer is divided by 2 plus one entity_secured_pace_nun_box 9 divided by oee burned akward potion tri tour all around divided by 3 divided by 4. No need to thank me.

Answer:

The British were determined to crush the rebellion.

They were criminals and made achieving independence more difficult.

Explanation:

Mau-mau were rebellions and wanted to push out British and other Europeans out of Kenya. Mau mau were also the members of the Kikuyu and were making independence more difficult, due to their rebellion attitude. They were a secret society of Kikuyu.

2) The British were determined to crush the rebellion.

3) They were criminals and made achieving independence more difficult.

After British victory in World War II, Kenyatta received a request to return to Kenya in September 1946, sailing back that month. He decided not to bring Edna—who was pregnant with a second child —with him, aware that if they joined him in Kenya their lives would be made very difficult by the colony's racial laws. On his arrival in Mombasa, Kenyatta was greeted by his first wife, Grace Wahu and their children. He built a bungalow at Gatundu, near to where he was born, and began farming his 32-acre estate.

• But,copper is not a ferromagnetic metal and that's why we cannot change the copper into any kind of magnets

Explanation:

With the use of wave speed formula, below are the answers to the questions

1. C

2. C

3. D

4. B

All the question centered on wave speed, wavelength and wave frequency. The relationship between these three quantities is;

wave speed = wavelength x frequency

That is,

V = Fλ

1. The given parameters are;

V = 1,500 m/s

F = 5 Hz

wavelength λ = V/F = 1500/5 = 300 m

2.) Given that the wavelengths ranging from 2.75 to 16.5 meters and the speed of sound is approximately 330 m/s

When wavelength = 2.75 m

F = V/ λ = 330 / 2.75 = 120 Hz

When wavelength = 16.5 m

F = V/ λ = 330 / 16.5 = 20 Hz

Therefore, the frequencies of thunder humans hear ranges from 20 Hz to 120 Hz

3.) Since the two waves are similar, they will be travelling at the same speed. That is,

Wave speed of X = Wave speed of Y

For wave X and Y respectively;

F = 200 Hz and 700 Hz

λ = 35 m and λm

Find λ of Y by equating the two wave speed. That is,

Fλ for X = Fλ for Y

200 x 35 = 700 λ

λ = (200 x 35)/ 700

λ = 7000 / 700

λ = 10 m

Therefore, The wavelength for wave Y is 10 m

4.) Given that the sea lions  frequencies are ranging from 500 to 4,000 hertz. And the speed of sound in sea water is approximately 1,500 m/s

By using the same formula,

V = Fλ

Make wavelength the subject of formula

λ = V / F

When F = 500 Hz

λ  = 1500/500 = 3 m

When F = 4000 Hz

λ =  1500/4000 = 0.375 m

Therefore,  the approximate wavelengths of sound with which the California sea lions communicate is of the range 0.375 m to 3 m
