What happens to waves near the shore?
Answers
Answer As a wave travels across the open ocean, it gains speed. When a wave reaches a shallow coastline, the wave begins to slow down due to the friction caused by the approaching shallow bottom. ... Think of it like driving a car at high speed and then slamming on the breaks. Everything is going to fly to the front.:Waves at the Shoreline: As a wave approaches the shore it slows down from drag on the bottom when water depth is less than half the wavelength (L/2). The waves get closer together and taller. ... Eventually the bottom of the wave slows drastically and the wave topples over as a breaker. hope this helps have a nice night❤️❤️❤️

Abby is writing a biography of Isaac Newton. He was a brilliant English scientist who developed the law of universal gravitation in the 1600s. Newton also developed laws of motion and ideas about inertia. His laws and ideas were used in many subjects such as physics, astronomy, and mathematics. Explain inertia using Newton's first law of motion. Give an example of inertia.
Answers
Answer:
Over several years, Newton worked until he had developed the law of universal gravitation, which debuted in his book Mathematical Principles of Natural Philosophy (1869). This idea stood until the concepts of quantum theory and relativity were posed in the mid 19th century.

Describe how the motion of the particles within the popcorn changes as thermal energy is transferred. How do they start out? How does that change? What other transformations occur?
Answers
Answer:
Generally, when thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three methods of thermal energy transfer: conduction, convection, and radiation. ... Convection transfers thermal energy through the movement of fluids or gases in circulation cells.
Explanation:
Answer:
Why do you think transferring energy into or out of a substance can change the molecules’ freedom of movement?

5. What do you think? At a baseball game, when you are far from the batter, you might see the batter hit the ball before you hear the sound of the hit. Why do you think this
happens?
Answers
Answer:
The speed of sound in air is lower compared to in solids and liquids.
Explanation:
Sound is a wave that can be generated by a vibrating body. Its speed through different media differs due to the nature of the media.
Since the molecules of solids are closely packed, sound can be easily transferred from one molecule to another at a faster rate. Thus, the high speed of sound in solids.
In liquids, the molecules are not as closely packed as solids. So that the speed of sound though liquids is lower compared to that of solids. Gases has its molecules farther apart, thus making the speed of sound through it the lowest compared to solids and liquids.
Therefore the sound of the batter hitting the ball is heard latter, due to its lower speed through the air.

Answers
Answer:
The table can be used to predict the properties of elements, even those that have not yet been discovered. Columns (groups) and rows (periods) indicate elements that share similar characteristics. The table makes trends in element properties apparent and easy to understand. The table provides important information used to balance chemical equations. Atoms are important because they form the basic building blocks of all visible matter in the universe. There are 92 types of atoms that exist in nature, and other types of atoms can be made in the lab. The different types of atoms are called elements. Hydrogen, gold and iron are examples of elements comprised of unique types of a single kind of atom.

245 ml
345 ml
123 ml
250.mL
Answers
Answer:
245 ml
Explanation:
rfdhccchhhgugvhh
The original volume of the sample of hydrogen is 250 mL. The correct option is the fourth option 250mL
From the question,
We are to determine the original volume of the hydrogen.
To do this,
We will use the Boyle's law formula
Boyle's law states that "the volume of a fixed mass of gas is inversely proportional to its pressure, provided that the temperature remains constant."
From Boyle's law we have that
P₁V₁ = P₂V₂
Where P₁ is the initial pressure
V₁ in the initial volume
P₂ is the final pressure
and V₂ is the final volume
From the question,
P₁ = 1.5 atm
P₂ = 0.50 atm
V₂ = 750 mL
Put the above parameters into the Boyle's law equation
P₁V₁ = P₂V₂
Then, we get
1.5 × V₁ = 0.50 × 750
1.5 × V₁ = 375
∴ V₁ = 375 ÷ 1.5
V₁ = 250 mL
Hence, the original volume of the sample of hydrogen is 250 mL. The correct option is the fourth option 250mL

5. The entrance of a science museum features a funnel into which marbles are rolled one at a time. The marbles circle around the wall of the funnel, eventually spiraling down into the neck of the funnel. The internal radius of the funnel at the top is 0.54 m. At the bottom, the funnel's neck nar- rows to an internal radius of 0.040 m. A 2.5 x 10-2 kg marble begins rolling in a large circular orbit around the funnel's rim at 0.35 rev/s. If it continues moving in a roughly circular path, what will the marble's angular speed be as it passes throught the neck of the funnel? (Consider only the effects of the conservation of angular momentum.)
Answers
Answer:
400.7886829 rad/s
Explanation:
First we have to turn our 0.35 rev/s into rad/s using the equation
(Xrev/s)*2pi=Xrad/s we can plug in .35*2pi=.7pi rad/s
Now we can us the equation m_1*v_1*r_1^2=m_1*v_2*r_2^2 we can plug in the given. Because the mass remains the same we can cross it off of both sides giving us just: v_1*r_1^2=v_2*r_2^2
(.7pi)*(.54)^2=(v_2)*(.04)^2
(.20412pi)=(v_2)*(.0016) [.20412pi=.6412618925]
then using division on both sides we get
(.6412618925/.0016)=v_2=400.79rad/s(This answer is rounded to the nearest hundreth)

The marble's angular speed as it passes through the neck of the funnel is 36.225 rev/s.
What is the conservation of angular momentum?The conservation of angular momentum states that the angular momentum of an object is conserved when there is no external torque acting on it.
We have,
The marble is rolling in a large circular orbit around the rim of the funnel. The angular momentum of the marble can be expressed as:
L = Iω
where L is the angular momentum, I is the moment of inertia, and ω is the angular velocity.
Now,
Since the marble is rolling in a circular orbit around the rim of the funnel, we can approximate its moment of inertia as a point mass rotating around a fixed axis.
The moment of inertia of a point mass rotating around an axis is given by:
I = mr²
where m is the mass of the marble and r is the radius of the circular orbit.
At the top of the funnel,
The radius of the circular orbit is equal to the internal radius of the funnel,
r = 0.54 m.
At the bottom of the funnel,
The radius of the circular orbit is equal to the internal radius of the funnel's neck,
r = 0.040 m.
Now,
Using the conservation of angular momentum,
We can equate the angular momentum of the marble at the top of the funnel to the angular momentum of the marble at the bottom of the funnel.
[tex]I_1W_1 = 1_2W_2[/tex]
Substituting the expressions for the moment of inertia at the top and bottom of the funnel, and solving for [tex]W_2[/tex].
[tex]W_2[/tex] = [tex](I_1/I_2)[/tex][tex]W_1[/tex]
[tex]W_2[/tex] = (m[tex]r_1^2[/tex])/(m[tex]r_2^2[/tex]) [tex]W_1[/tex]
[tex]W_2[/tex] = (r1/r2)^2[tex]W_1[/tex]
[tex]W_2[/tex] = (0.54/0.040)²(0.35 rev/s)
[tex]W_2[/tex] = 36.225 rev/s
Therefore,
The marble's angular speed as it passes through the neck of the funnel is 36.225 rev/s.

Explanation:
In this exercise we are asked to find the distance that the spring is compressed, let's use the concepts of conservation of energy
starting point. Before touching the spring
Em₀ = K = ½ m v²
final point. When the spring has maximum compression
[tex]E_{f}[/tex] = [tex]K_{e}[/tex] = ½ k x²
as there is no friction the mechanical energy is conserved
Em₀ = Em_f
