For questions like this there are only a couple of possible equations you need to look at :)

In this case the equation for Kinetic energy (energy of motion) is:

K_{E} = (0.5*m) * v^2

Simply plug in the mass and velocity variable given in the question and you have your answer :)

Forces of attraction limit the motion of particles most in
Alexandra [31]

<em><u>Answer:</u></em>

Solids

<em><u>Explanation:</u></em>

<u>Solids</u> have definite shapes and definite volumes. The forces of attraction between the molecules of a solid substance are strong and the intermolecular spaces are very small. Due to this, the motion of molecules within a solid substance are very difficult that they only vibrate in their positions.

<u>For liquids</u>, they have definite volumes and indefinite shapes. The forces of attraction between the molecules of a liquid are intermediate and the the intermolecular spaces are intermediate as well. Due to this, the motion of molecules within a liquid substance is not as difficult as it is within solids.

Finally, <u>for gases</u>, they have indefinite shapes and indefinite volumes. The forces of attraction between the molecules of a gas are weak and the intermolecular spaces are large. Due to this, the motion of particles of gas is very easy.

Hope this helps :)

What statement is true about the part of the electromagnetic spectrum that is visible to the human eye?
Alja [10]
Based on the options above, I see how the last option would actually be most fitting to how "the part of the electromagnetic spectrum that is visible to the human eye". This would be in separate parts, which would be divided into a certain number, which would actually be only 7 ranges of wavelengths. And therefore, this last statement would actually go very well and it would actually be the correct answer. And this would all relate to how <span> the part of the electromagnetic spectrum that is visible to the human eye, it's based on it's own 7 division parts that it has. 

Your answer: </span>\textsf{It is divided into seven ranges of wavelengths}

In what ways would organisms living in very deep water need to be specialized?
Nady [450]

Organisms living in great depths of water bodies like oceans and lakes need to be adapted for two (2) things especially; high water pressure and vision in darkness

The water column above from deep in the water can cause lots of hydrostatic pressure on the organisms’ cells. Also the fact that light cannot penetrate to great depth of water due to diffusion means the organisms must live in darkness.

Explanation:

It has been shown that cells from Piezophile bacteria have a high percentage of fatty acids in their membranes to prevent the cells from compacting solid from the high pressure.

Most of the organisms are also detritivores and use chemosynthesis for the autotrophs because light cannot reach these depths and hence photosynthesis is not possible.  Organisms with eye vision are adapted to high wavelength light that can at least reach greater depths before diffusing. Nonetheless natural selection would favour use of sight for most organisms in this benthic region.
