how can an xray image show differences between bone and soft tissues, such as muscles and lungs? How might the atoms that make u
enyata [817]

Answer with Explanation:

1. An "x-ray image" shows the difference between the bones and soft tissues because the <em>bones appear white in color </em>while the <em>soft tissues appear gray in color.  </em>

2. The reason behind the difference in the appearance of bones and soft tissues on the x-ray film is their<em> density.</em> <u><em>Bones are denser than soft tissues</em></u>, which means that<em> its atoms are closely-knitted when compared to the soft tissues that are far apart from each other. </em>This allows the<em> </em><em>x-ray radiation to be absorbed by the bone </em>while <em>it passes through most of the soft tissues.</em>

This is the reason why pregnant women are advised not to undergo an x-ray examination because<u><em> the fetus is denser and it will surely absorb the x-ray radiation.</em></u>

What dissolved species are present in a solution of NaClO4?
Nadusha1986 [10]

Assuming that the solution is simply an aqueous solution so that it is purely made of NaClO4 (the solute) and water (the solvent), then I believe the dissolved species would only be the ions of NaClO4, these are:

Convert 645 Newtons per quart to tons per liter. (The picture is a conversion table for help)
brilliants [131]

Answer:

0.067 ton/Litre.

Explanation:

645 Newtons per quart to tons per liter.

We'll begin by converting 645 Newton/quart to gram/quart (g/q). This can be obtained as:

1 N/q = 100 g/q

Therefore,

645 N/q = 645 N/q × 100 g/q / 1 N/q

645 N/q = 64500 g/q

Therefore, 645 Newton/quart is equivalent to 64500 grams per quart.

Next, we shall convert 64500 grams per quart to pounds per quart. This can be obtained as follow:

454 g/q = 1 pound/q

Therefore,

64500 g/q = 64500 g/q × 1 p/q / 454 g/p

64500 gram/quart = 142.07 pound/quart

Therefore, 64500 gram/quart is equivalent to 142.07 pound/quart.

Next, we shall convert 142.07 pound/quart to ton/quart. This can be obtained as follow:

2000 p/q = 1 ton/q

Therefore,

142.07 p/q = 142.07 pq × 1 ton/q / 2000 p/q

142.07 pound/quart = 0.071 ton/quart

Therefore, 142.07 pound/quart is equivalent to 0.071 ton/quart.

Finally, we shall convert 0.071 ton/quart to ton/litre. This can be obtained as follow:

1 ton/q = 1/1.06 ton/L

Therefore,

0.071 ton/q = 0.071 ton/q × 1/1.06 ton/L / 1 ton/q

0.071 ton/quart = 0.067 ton/Litre

Therefore, 0.071 ton/quart is 0.067 ton/Litre.

From the above illustration, 645 Newton/quart is equivalent to 0.067 ton/Litre.
