Answer : The correct option is, gamma

Explanation :

Penetration power : It is the movement of rays or the particles through an object.  We know that the more the energy of a particle, the more will be the penetrating power.

The increasing order of the penetration power of alpha rays, beta rays, and gamma rays will be,

Alpha rays < Beta rays < Gamma rays

The penetrating power of the alpha, beta and gamma rays varies greatly.

(1) The alpha particles are restricted by the paper.

(2) The beta particles can pass through the paper but it can not pass through the aluminum foil.

(3) The blocking of gamma rays is very difficult. It can be blocked only by concrete, lead, or other heavy shielding.

Hence, the radiation can only be stopped by thick layers of dense metal is, gamma.

Gamma rays have the highest penetrating power so it can only be stopped by thick layers of dense metal. :)

Do subatomic particles have mass
katovenus [111]

Answer:

Yes

Explanation:

Masses for the three subatomic particles can be expressed in amu (atomic mass units) or grams. For simplicity, we will use the amu unit for the three subatomics. Both neutrons and protons are assigned as having masses of 1 amu each.

With circulation, the heart provides your body with:
Ivanshal [37]
<h3>Answer:  D) all of the above</h3>

Explanation:

The lungs pump oxygen in and carbon dioxide out, which goes through the blood stream to help with the cell's energy needs.

Nutrients pass through the blood stream as well. The nutrients start with the digestive system (mouth, esophagus, stomach, small intestine) before going into the blood stream. The nutrients are building blocks to help make new cells when old ones die off.

When those cells die off, the body sheds them like dead skin, but internal dead cells are passed off as waste. This waste and other byproducts the body doesn't need passes through the blood stream as well.

In short, the blood stream is basically the highway to help get desired materials (eg: oxygen and nutrients) and get rid of waste (eg: carbon dioxide and other unwanted byproducts or dead cell material)

So that's why the answer includes A, B and C.

An 8.42 g piece of metal with a specific heat of 1.020 J g-1 k-1 wasn't heated to an unknown temperature. The metal was then pla
ANTONII [103]

Answer:

T = 61.344\,^{\textdegree}C

Explanation:

The heat received by water is equal to the heat rejected by the piece of metal. That is to say:

-Q_{piece} = Q_{water}

(8.42\,g) \cdot \left(1.020\,\frac{J}{g\cdot ^{\textdegree}C}  \right) \cdot (T - 20.40\,^{\textdegree}C)= (44.2\,g)\cdot \left(4.187\,\frac{J}{g\cdot ^{\textdegree}C} \right)\cdot (20.40\,^{\textdegree}C-18.50\,^{\textdegree}C)

\left(8.588\,\frac{J}{^{\textdegree}C} \right)\cdot (T-20.40\,^{\textdegree}C) = 351.624\,J

The initial temperature of the piece of metal is:

T = 61.344\,^{\textdegree}C
