Answer:

*The increase in thermal energy  the maximum emission of radiation changes according to Wien's law

*The increase in thermal energy  he intensity of the energy increases significantly, proportional to the fourth power of the temperature

Explanation:

When bodies heat up, the vibrations of their molecules and atoms increase, due to the energy, therefore the internal energy (Temperature) of the body also increases.

The increase in thermal energy relaxes in an increase in body temperature, when this happens the maximum emission of radiation changes according to Wien's law that gives a shift towards the visible as the temperature increases.

Furthermore, the intensity of the energy increases significantly, in a curve described by the Planck expression.

These increases are proportional to the fourth power of the temperature

Answer:

dust cloud

Explanation:

Stars are formed from the accumulation of the dust as well gases in the solar system. The dust and the gases collapses due to the the gravity forces and the stars are formed.

They are formed within the clouds of the dust and gases and are scattered in the galaxies. The stars are formed in a million of years from the dust clouds.

In the context, Abdul have a picture of a dust cloud which looks smoky and dusty which is the initial stage of the stars formation due to the gravity.  It is the region of the star that looks like a cloud of dust before the formation of the star.

Answer:

2.4m/s²

Explanation:

Given parameters:

Initial velocity  = 0m/s

Time 25s

Final velocity  = 60m/s

Unknown:

Acceleration  = ?

Solution:

Acceleration is the rate of change of displacement

      Acceleration  = [tex]\frac{Final velocity - Initial velocity}{time}[/tex]

    Acceleration  = [tex]\frac{60 - 0}{25}[/tex]    = 2.4m/s³

Answer: what is it in

Explanation:

Answer:

1. Displacement can be positive OR negative. The sign implies the direction of the displacement. 2. In one dimension the direction is indicated by the sign: negative if to the left and positive if to the right.

Answer: The greater an object's mass, the more gravitational force it exerts.

Explanation: So, to begin answering your question, Earth has a greater gravitational pull than the moon simply because the Earth is more massive. Sorry if I get this wrong. I am in 5th grade! ♥

The gravitational attraction between the Sun and Earth is stronger than the attraction between the Sun and the Moon, principally because of the Sun's greater mass and greater distance from Earth.

An object's mass affects how much gravitational pull it exerts. Both the Earth and the Moon are much less massive than the Sun. Approximately  330,000 times more massive than the Earth, and roughly 27 million times more massive than the Moon, is the Sun. Because of the Sun's greater mass, its gravitational pull is thus much stronger.

The strength of the gravitational force between two objects is greatly influenced by their distance from one another. The Sun and Earth are separated from one another by a far smaller distance than the Sun and Moon. The Sun is located roughly 150 million kilometers from Earth, while the Moon is located roughly 384,400 kilometers from the Sun on average. The inverse square law asserts that the gravitational force decreases with increasing distance, and that it is only one-fourth as strong when two objects are twice as far apart.

Hence, the gravitational force between the sun and earth is larger than the sun and the moon due the mass of the sun and earth is greater than the moon and sun. The distance between the sun and the earth is comparatively smaller than the distance between the sun and the moon.

Answer:

ALWAYS ( in all cases and at all times)

Explanation:

From Newton's 3rd Law of motion which states that every action that occurs (force) there will be equal as well as opposite reaction. Therefore as the man is pushing the chair exerting 50N force, the chair also is is exerting equal force as well as opposite force on him as he is pushing it

That's the Ampere.

1 Ampere = 1 Coulomb of charge per second.

Answer:

The wavelength of the waves traveling along the string is 12 meters.

What is a Wavelength?

Given:

Waves propagate along the stretched string at speed = 8.0 m/s

The end of the string vibrates up and down once every 1.5 s.

∴ Time = 1.5 s

We have to find the wavelength of the waves.

We know,

⇒ Time = 1/frequency

⇒ 1/frequency = 1.5

Now

⇒ speed = frequency × wavelength

⇒ wavelength = speed / frequency

⇒ wavelength = 8 × 1.5

⇒ wavelength = 12 m

Therefore, the wavelength of the waves traveling along the string with given speed is 12 m.

Answer:

[tex]K=120[/tex]

Explanation:

From the question we are told that

Length of spring   [tex]l_1=0.5m[/tex]

Length of stretched [tex]l_s=1m[/tex]

Potential energy of spring [tex]E=15J[/tex]

Generally equation for energy stored is mathematically given as

[tex]U=1/2K \triangle x^2[/tex]

[tex]K=\frac{2U}{\triangle x^2}[/tex]

[tex]K=\frac{2*15}{ 0.5^2}[/tex]

Therefore value of the spring constant in N/m? is given as

[tex]K=120[/tex]

The value of the spring constant is 120 N/m.

The spring constant of the spring is calculated by applying the principle of conservation of energy as follows;

[tex]\frac{1}{2} k \Delta x = U[/tex]

Where;

The value of the spring constant is calculated as follows;

[tex]k = \frac{2U}{\Delta x} \\\\k = \frac{2\times 15}{0.5^2}\\\\k = 120 \ N/m[/tex]

Explanation:

Given parameters:

Mass of freight train  = 270700kg

Acceleration = 40m/s²

Unknown:

Force acting on the train = ?

Solution:

From Newton's second law of motion, we know that:

       Force  = mass x acceleration

So;

        Force  = 270700 x 40   = 1.08 x 10⁷N

Answer:

147N

Explanation:

pressure = 7pa

area= 21m

force=?

now,

p = f/a

7 = f/21

f = 21×7

therefore, f = 147N.

Answer:

Atoms are so much smaller than the wavelength of visible light that the two don't really interact.

Explanation:

To put it another way, atoms are invisible to light itself.

Visible light has a wavelength that ranges from 400 to 700 nm. Atoms, in contrast, typically have a diameter of between 0.1 and 0.3 nm. The size difference is greater than a thousand times, even with straightforward calculations.

Over 500,000 times of magnification are possible using an electron microscope, which is sufficient to observe a great deal of information inside cells.

The electron microscope comes in a variety of varieties. Atoms and nanoparticles can be observed with the use of a transmission electron microscope.

In a chemical reaction, atoms cannot be formed or destroyed, since they are indivisible units. The mass and chemical characteristics of each atom of a specific element are the same.

Therefore, the atom's structure is invisible to visible light.

I think this may be a trick question... so from my reasonable logic, I'm gonna say no because more often then not they are attached to the wall with nails/screws. Or they are hanging.

So they could come off. Also if someone was desperate, they could always grab a chainsaw and force it off of the wall. Not a great idea though, then the wall would be broken!! Most likely the clock too!
