X-rays are used instead of visible light because X-rays have shorter ______________ than visible light, allowing them to produce images of much greater detail.

Answers

Answer 1

X-rays have shorter wavelength than visible light. But that's hardly the reason that they're used for medical imaging. xrays have much higher frequencies then visible light which means they have much greater penetrating ability. with xrays you can see inside the body. you can't do that with a visible flashlight no matter how bright and powerful it is.

Answer 2

i think it might be wavelengths.. but don't quote me on that

5 m/s^2
10 m/s^2
10 m/s
15 m/s

Answers

The answer is 10m/s^2
This is because a={v-u}/t
a={15-10}/0.5=5/0.5=10m/s^2

what is the energy that moves your arms and legs

Answers

Your body's cells hold chemical potential energy, which is stored when you are not moving. Then, it changes to kinetic energy as you move, which 'powers' your arms and legs.

which of the following elements is the most reactive?
Beryllium
Calcium
Magnesium
Barium

Answers

Answer;

Barium

Explanation;

Group 2 metals get more reactive as we go down the group. The alkaline earth metals are the elements in Group 2 of the Periodic Table: beryllium, magnesium, calcium, strontium, barium, and radium. alkaline earth metals have low melting points and low densities for metals.

The decrease in reactivity down the group can be explained by the increase in ease at losing two outer electrons as we descend the group. The loss of electrons becomes easier due to the decreasing ionization energy required. Ionization energy decreases due to extra shielding from inner shells and increase in distance from the nucleus.

Answer: The correct answer is Barium.

Explanation: We are given some elements which belong to group 2 of the periodic table. These elements are considered as metals.

Reactivity of metals are defined as the ability of a metal to loose electrons easily.

In a periodic table, as we move down the group, the ability to loose the electrons increases and as a result, the reactivity of elements increases.

From the given elements, the last element which belongs to group 2 is Barium.

Hence, the most reactive element is Barium.
