Answer:

Oxygen is an element that can be a solid, liquid or gas depending on its temperature and pressure. In the atmosphere it is found as a gas, more specifically, a diatomic gas. This means that two oxygen atoms are connected together in a covalent double bond.

Answer:

Elastic collision

Explanation:

An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic collisions. Supposed two similar trolleys are traveling toward each other with equal speed.

Answer:

Amplitude

The amplitude ( ) of a wave is the distance from the centre line (or the still position) to the top of a crest or to the bottom of a trough .

Explanation:

Hope it helps

The distance traveled by a wave crest in a given time is defined as: D. speed.

A wave can be defined as a disturbance in a medium that progressively transport energy from a source to another location, especially without the transportation of matter.

Some examples of the characteristics of a wave include the following:

In Science, speed refers to the distance traveled by a wave crest in a given time.

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

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.

Explanation:

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: Newton’s Third Law of Motion

Explanation:

USATestPrep❤️

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:

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.

In the solids, convection can not occur. Convection can only be done in the fluids.

Under the effect of gravity, hotter, less dense material rises while colder, denser stuff sinks, resulting in heat transfer"Convection is the ultimate mode of energy transmission to the surface"

There are three modes of the heat transfer;

1. Conduction

2. Convection

3. Radiation

Convection occurs in the fluid which is liquid and gases. Convection never occurs in the solid.

Hence option B is correct.

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.

The British were determined to crush the rebellion.

They were criminals and made achieving independence more difficult.

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.
