Explanation:

I am 95 percent sure the answer in C

Answer: C

Explanation:

Answer:

 x = 0.537 m

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

          ½ m v² = ½ k x²

          x = [tex]\sqrt{\frac{m}{k} }[/tex]  v

let's calculate

          x = RA[tex]\sqrt{\frac{4.0}{125} }[/tex]  3.0

          x = 0.17888 3.0

          x = 0.537 m

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.

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:

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.

Answer:

Why do you think transferring energy into or out of a substance can change the molecules’ freedom of movement?

Explanation:

We know that transferring energy can cause a change in molecules' freedom of movement. Another way to say this is that transferring energy into or out of a substance can cause a phase change.

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❤️❤️❤️

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.
