Answer:

he at 100k

Explanation:

All particles have energy, and the energy varies depending on the temperature the sample of matter is in, which determines if the substance is a solid, liquid, or gas. Solid particles have the least amount of energy, and gas particles have the greatest amount of energy.

The temperature of a substance is a measure of the average kinetic energy of the particles. A change in phase may occur when the energy of the particles is changed.

There are spaces between particles of matter. The average amount of empty space between molecules gets progressively larger as a sample of matter moves from the solid to the liquid and gas phases.

Key Terms

kinetic molecular theory: Theory of treating samples of matter as a large number of small particles (atoms or molecules), all of which are in constant, random motion

kinetic: Of or relating to motion.

lattice: A regular spacing or arrangement of atoms/molecules within a crystal.

phase: A component in a material system that is distinguished by chemical composition and/or physical state. Matter can exist in the solid, liquid, and gaseous phases.

The kinetic molecular theory of matter offers a description of the microscopic properties of atoms (or molecules) and their interactions, leading to observable macroscopic properties (such as pressure, volume, temperature). An application of the theory is that it helps to explain why matter exists in different phases (solid, liquid, and gas) and how matter can change from one phase to the next.

All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, liquid, or gaseous state. Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy.

Which of the following is true about green light? a) It has a greater frequency than red light and blue light. b) It has a small
lesantik [10]

Answer:

c) It has a greater frequency than red light but a smaller frequency than blue light.

Explanation:

According to the relation:

c = frequency × Wavelength

The higher the frequency, the lower the value of wavelength

The order of wavelength is:

Violet < Indigo < Blue < Green < Yellow < Orange < Red

Stated above, frequency is inversely proportional to the wavelength. Thus, the order of wavelength is:

Violet > Indigo > Blue > Green > Yellow > Orange > Red

Thus,

<u>Green light has lower frequency than blue light and higher than red light.</u>

Convert 3.5revolutions to radians.
olga55 [171]

As we know that

1 revolution = 2\pi radian

now we know that

3.5 revolution = 3.5 rev\times \frac{2\pi rad}{1 rev}

3.5 rev = 21.98 rad

so it is 21.98 radian

A 2.00 meter long horizontal plank whose mass is 3.00 kg is placed so that the very end (the right end) rests on a retaining wal
avanturin [10]

Answer:

R_g=\frac{61}{7} =8.7143\ N

R_w=45.1857\ N

Explanation:

Given that:

  • mass of plank, m=3\ kg
  • length of plank, l=2\ m

From the image we can visualize the given situation.

Consider the given plank to be mass-less and having a uniformly distributed mass of 1.5 kg per meter.

<u>Now in the balanced condition:</u>

  • \sum F=0

R_g+R_w=(3+2.5)\times 9.8

R_g+R_w=53.9\ N .......................(1)

  • \sum M_w=0

1.75\times R_g=3\times 1+(2.5\times 9.8)\times 0.5

R_g=\frac{61}{7} =8.7143\ N ...........................(2)

is the force acted by the tailgate on the plank.

<u>Substitute the value from (2) into (1):</u>

R_w=45.1857\ N is the force acted by the wall upon the plank.
