Would sound waves travel slower through air at the north pole or at the equator?.

Answers

Answer 1

yes they would travel slower at the north pole than the equator because the air is more dense and is harder to pass through

Answer 2

Yes, sound waves would travel slower at the North Pole than at the equator because the air is denser and is harder to pass through.

What are equators?

The Equator is the midline of the earth.  A vibration results in a sound. We refer to these motions as "sound waves." Sound waves require a specific medium to travel through. The three different types of media are solid, liquid, and gas.

Keep in mind that since a "solid medium" is denser than the other two, sound waves move through it more quickly. Because water is more densely packed with particles than gas is, sound waves travel faster in liquid than in gas (such as air).

Therefore, yes, because the air is heavier and more difficult to get through at the North Pole than it is at the Equator, sound waves would move more slowly there.

Explanation:

A rock is projected from the edge of the top of a building with an initial velocity of 12. 2 m/s at an angle of 63° above the horizontal. The rock strikes the ground a horizontal distance of 25 m from the base of the building. Assume that the ground is level and that the side of the building is vertical. What is the time?.

Answers

The rock travels a horizontal distance x after time t of

x = (12.2 m/s) cos(63°) t

If it hits the ground 25 m away from where it was thrown, then for some time t we have

25 m = (12.2 m/s) cos(63°) t

Solve for t :

t = (25 m) / ((12.2 m/s) cos(63°))

t ≈ 4.5 s

Two football players are running toward each other. One football player has a mass of 105 kg and is running at 8. 6 m/s. The other player has a mass of 90 kg and is running at -9. 0 m/s. What is the momentum of the system after the football players collide? 93 kg · m/s 1,713 kg · m/s. 810 kg · m/s. 903 kg · m/s.

Answers

The correct answer is P = 1740 kg · m/s, we got this answer by applying the momentum expression which is P = Δ(mv), based on the fact that the mass is not constant

Given data

Mass of Player one = 105kg

Mass of Player two = 93Kg

The Velocity of Player one = 8.6m/s

The Velocity of Player two = -9.0m/s (the negative sign indicates the opposite direction to player one)

Applying Newton’s Second Law in Terms of Momentum because the mass is not constant

When Newton’s second law is expressed in terms of momentum, it can be used for solving problems where mass varies,

We also want to assume that the players stuck together after the collision

An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved due to the action of internal friction.

P = M1V1 + M2V2

P= 105*8.6+93*9.0

P = 903 +837

Answers

Answer:

Edge says Fecundity

Explanation:

Fecundity is the biological capacity of an organism to conceive a child - in conjunction with another organism. For this to occur it is necessary that the man and the woman be fertile, that is, they have fertility. A person's fertility is measured by the number of ovules / seeds that can be fertilized. After fertilization, the fetus grows in the gestational process and becomes a baby.

The correct word from the list that best fits the definition of the biological capability to bear children is fecundity. The correct option is E.

What is childbearing?

Women can theoretically become pregnant and give birth from puberty, when they begin having periods, to menopause, when they cease having them. The reproductive years of the average woman last from 12 to 51 years.

The biological ability of one organism to conceive a child in collaboration with another creature is known as fecundity. Both the man and the woman must be fertile, or have fertility, for this to happen.

The quantity of ovules or seeds that can be fertilized is used to determine a person's fertility. The fetus develops during the gestational period after conception to become a baby.

A mixture of iron, salt, and sand can be separated using a magnet, water, a filter, and a hot plate. This separation _____.

Answers

Answer:

i think mixture

Explanation:

sorry if it wrong(tried my best)

Answer:

This is an example of a mixture that can be separated with simple separation techniques based on the physical properties of the mixtures. Magnetism, and filtration and evaporation

Iron is a magnetic material, but salt and sand are not, therefore, the iron can be separated from the mixture with the use of a magnet.

Salt and sand are mixable. Salt is soluble in water, but sand is not. Therefore by adding the sand and salt to water, the salt will dissolve,in the water(solvent) to form a salt solution. But the sand can be separated out of the solution by filtration with the filter paper inserted into a funnel which allows the salt solution to pass through while restricting the sand.

The sand would be removed by the filter paper, while the solution passes through.

The salt solution and some sand residues are placed in an evaporating dish and heated at low temperatures. The water from the solution evaporates, leaving the salt behind.

What is the frequency of a sound source that produces the same wavelength in 20∘c air?.

Answers

Based on the standard formula and data in the question, the frequency of a sound source that produces the same wavelength in 20∘c air is "115.87Hz."

What is the frequency of a sound source?

The frequency of a sound source is the quantity of waves that move through a point per unit of time.

Typically, a sound wave arises from a source vibrating at a frequency f, propagates at v, and has a wavelength λ.

Therefore, in this case, we have

Velocity (v) of sound in air = 343 m/s

Wavelength (λ) = 2.96 m

Frequency (f) =?

f = v ÷ λ

f = 3.43m/s ÷ 2.96m

=> 115.87Hz

Hence, in this case, it is concluded that the correct answer is 115.87Hz.

Answers

Answer:

C. 4.29 years

Explanation:

The computation of the payback period is shown below:

Payback period = Initial investment of the equipment ÷ Cash flows

where,

Initial investment = $30,000

And, the cash flows is

= $8,500 - $1,500

= $7,000

So the payback period is

= $30,000 ÷ $7,000

= 4.29 years

By dividing the initial investment by the cash flows we can get the payback period and the same is applied above.

Which correctly lists the three features shown in the photo? folds, strike-slip faults, and anticlines anticlines, synclines, and folds synclines, normal faults, and strike-slip faults normal faults, folds, and anticlines.

Answers

Anthe answer is A

Explanation:

The correct list of the three features shown in the photo are folds, strike-slip faults, and anticlines. The correct option is A.

What are folds?

On a geological timescale, modern folds are those that first appeared in the Tertiary Period (between 65 million and 2.5 million years ago). Geological formations known as faults are the result of internal forces that are inclined or vertical (top-down).

The transcurrent fault, which is also known as a horizontal fault, develops when there is movement in the horizontal plane between two blocks.

It is more prevalent in regions where two tectonic plates converge since these zones also experience horizontal movement. When two or more of the tectonic plates of Earth are forced together, fold mountains are formed.

Therefore, the correct option is A, folds, strike-slip faults, and anticlines.
