What is lowest to highest radiation energy

E α particles > E β particles > E γ rays , where E= energy

Explanation:

When an unstable atomic core disintegrates due to its instability , a particle emission called radioactive decay – or radiation energy - occurs (this occurs when there is an excess of energy)

There are, basically, 3 types of radiation energy:

-Alpha particles (α): these are Helium particles, with just 2 protons and 2 neutrons. Alpha particles have the most mass, for which its capacity to penetrate all materials is quite limited (they don´t pass through a thin sheet of paper or body´s skin)

Alpha particles have a high amount of energy

-Beta particles (β): these are electrons (e-) or positrons (e+), and have a much less mass than Alpha particles, for which they have more capacity to penetrate all materials (they can penetrate a sheet of paper, however, they are not able to penetrate a thin sheet of metal

These particles have much less energy than Alpha particles

-Gamma rays (γ): these are electromagnetic radiations, hence they don´t have mass nor energy, and so they are able to penetrate all materials (actually, it is necessary to use a thick cement wall to stop this type of rays)

So, considering the energy (E) for the above description:

E α > E β > E γ rays

You may also have another perspective (when it comes to energy) using the following formula:

E=mc² which it let us see that energy is directly proportional to mass (the more mass, the more energy)

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
