Answer : The correct option is, only alpha particles.

Explanation :

Penetration power : It is defined as the movement of the rays or the particles through the object.  As more the energy of a particle, the more will be the penetrating power.

The ascending or increasing order of the penetration power of the particles will be :

Alpha rays < Beta rays < Gamma rays

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

  • The alpha particles can be stopped by the paper, cloth, human skin.
  • The beta particles can pass through the paper, cloth, human skin but it can not pass through the aluminum foil.
  • The blocking of gamma rays is very difficult. It can be stopped only by concrete, lead, or other heavy shielding.

Hence, the particles can be stopped by human skin is only alpha particles.

Archy [21]
Energy transferred per second in given area:
8000 x 3.9 / 10000
Energy transferred = 3.12 J

Using Planck's equation:
E = nhc/λ
n = (3.12 x 510 x 10⁻⁹) / (3 x 10⁸ x 6.63 x 10⁻³⁴)
n = 8 x 10¹⁸ photons

Which reaction is single replacement?
Tatiana [17]
<span>Among the given choices, the third option is the only one which illustrates single replacement. (3)H2SO4 + Mg --> H2 + MgSO4 A single replacement is also termed as single-displacement reaction, a reaction by which an element in a compound, displaces another element. It can be illustrated this way: X + Y-Z → X-Z + Y</span>
