The answer is yes. If itbid longer it is lower. shorter me and higher
Answer
given,
storage coefficient, S = 6.8 x 10⁻⁴
thickness of aquifer, t = 50 m
porosity of the aquifer, n = 25 % = 0.25
Density of the water, γ = 9810 N/m³
Compressibilty of water,β = 4.673 x 10⁻¹⁰ m²/N
We know,
S = γ t(nβ + α)
where, α is the compressibility of the aquifer
6.8 x 10⁻⁴ =9810 x 50 x (0.25 x 4.673 x 10⁻¹⁰+ α)
α = 1.269 x 10⁻⁹ m²/N
Expansability of water
= n t β γ
= 0.25 x 50 x 4.673 x 10⁻¹⁰ x 9810
= 5.73 x 10⁻⁵
In the holes there is brass "fingers" that grab the plug prongs when you plug it in. So it's made out of brass or copper.
Answer:
A) 8π ft²/ft
B) 24π ft²/ft
C) 48π ft²/ft
Explanation:
Surface area of the spherical balloon is not clear here but it is supposed to be;
S = 4πr²
where:
r is the radius of the spherical balloon
So thus, the rate of change of the surface area of the spherical balloon by its radius will be:
dS/dr = 8πr
A) at r = 1ft;
dS/dr = 8 × π × 1
dS/dr = 8π ft²/ft
B) at r = 3 ft;
dS/dr = 8 × π × 3
dS/dr = 24π ft²/ft
C) at r = 6ft;
dS/dr = 8 × π × 6
dS/dr = 48π ft²/ft
