bearhunter [10]

Answer:

The answer is 6.4 × 10^{-20} Joules

Explanation:

This question wants to effectively test your knowledge of the names of the negative powers of 10, so first of all, before calculating, let me explain what each of the symbols in the units given in the question means:

Force = 8.0 pN = 8.0 × 10^{-12} N

displacement = 8.0 nm = 8.0 × 10^{-9} N

Now let us calculate the work.

work = Force × Displacement

work = 8.0 × 10^{-12}  × 8.0 × 10^{-9} = 64 × 10^{-21}

= 6.4 × 10^{20} Joules (in standard form)

Which best blocks X-ray particles and can therefore be observed more closely through the use of this technology?
Vedmedyk [2.9K]

Answer:

The correct answer would be bones.

X-rays are high energy electromagnetic waves which have an ability to penetrate most of the biological tissues.

In the X-ray machine, a beam of high energy X-rays is passed through the filters and subject and then fall on the detector or photographic film to produce X-ray.

Dense tissues like bone, teeth, tumors et cetera blocks or stops most of the X-ray particles from reaching the detector or photographic film.

It forms glowing pictures on the X-ray film or photographic film.

The denser the material the brighter the image will be formed on the photographic film.
