c. sandstone in the zone of saturation

Explanation:

The best aquifer of all is a sandstone in the zone of saturation. An aquifer is a porous and permeable formation where groundwater can accumulate.

  • To be a good aquifer, a rock or soil must be porous and permeable.
  • Porosity is the amount of void spaces present in a rock.
  • Permeability is the inter-connectivity of the pore spaces.

The zone of saturation is the zone below the water table where water is always present underground.

  • Sandstones have high porosity and permeability.
  • They are good aquifers when found at the zone of saturation.

A 0.1 mm sample of human blood has approximately 6000 red blood cells. An adult typically has 5.0 L of blood. How many red blood
olga55 [171]

 3.0 × 10¹¹ RBC's    (or)      3E11 RBC's


Solution:

Step 1: Convert mm³ into L;


As,


                                            1 mm³  =  1.0 × 10⁻⁶ Liters


So,


                                         0.1 mm³  =  X  Liters


Solving for X,


                       X  =  (0.1 mm³ × 1.0 × 10⁻⁶ Liters) ÷ 1 mm³


                       X  =  1.0 × 10⁻⁷ Liters


Step 2: Calculate No. of RBC's in 5 Liter Blood:


As given


                        1.0 × 10⁻⁷ Liters Blood contains  =  6000 RBC's


So,


                         5.0 Liters of Blood will contain  =  X  RBC's


Solving for X,


                      X  =  (5.0 Liters × 6000 RBC's) ÷ 1.0 × 10⁻⁷ Liters


                      X  =  3.0 × 10¹¹ RBC's


Or,


                     X  =  3E11 RBC's

nuclear reactions can be written out in equation form with information about the nuclei that are produced. in one to two sentenc
Umnica [9.8K]

Nuclear fusion involves the combination of two light nuclei to form a heavier nucleus with emission of energy.

A nuclear reaction equation is a representation of the change that takes place as one nucleus is converted to another. A nuclear transformation could be any of the following;

  • Nuclear fission
  • Nuclear fusion
  • Transmutation

We can know that a nuclear fusion is taking place when two nuclei come together to form a larger nucleus and emit energy. I would identify a nuclear fusion when;

  • Two light atom combine to give a larger nucleus
  • Tremendous energy is produced
