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.

they're not speaking to you and your family a very happy and prosperous new year and I will be there at first I thought it would be a good time to come by and see you soon
I believe it would be Boyle's Law
(P [is proportional to] 1/V)
P being pressure
V being volume
Answer:
The specific gravity of the gel is 1470.68
Explanation:
Given:
Volume 
Diameter of tank 
m
Pressure at surface 
atm
Height 
ft 
m
Pressure at bottom is given by,
Where 
, 
Here volume is 4.24
m
From pascal equation,
Find density of gel from above equation,
So specific gravity is given by,
ζ = 
ζ = 
ζ = 
Therefore, the specific gravity of the gel is 1470.68
