The water table is the
a. zone of aeration.
b. lower boundary of the zone of saturation.
c. upper boundary of the zone of saturation.
d. aquifer.

When You Look Up This Question

This Is What You Get

"The Water Table is the upper surface of the zone of saturation. ..."

But thats incorrect

That Rules Out B

Now My Answer Choices Are Slightly Different.

A. The Boundary Line Between The Zone Of Saturation And The Zone Of Aeration

B. The Boundary Between Layers Of Permeable And Impermeable Rock

C. The Upper Limit Of The Zone Of Aeration

D. Both A And C

We Know That A Is Incorrect. (B For Your Choices Above)

So We Can Rule Out @ Wrong Answers Just Right There.

That Leaves Us 2 Choices Left

B. The Boundary Between Layers Of Permeable And Impermeable Rock

C. The Upper Limit Of The Zone Of Aeration

Looking Up "Zone Of Aeration" You'll Find

"That it is the region between the earth's surface and the water table. The main components of this region are the soil and rocks. ... "

So For Your Answer Choices You Have

Leaving You 2 Choices Left

B. lower boundary of the zone of saturation.

D. aquifer

Looking Up "Permeable And Impermeable Rock" You'll Find

"Permeable surfaces allow water to percolate into the soil to filter out pollutants and recharge the water table. ..."

"Impermeable surfaces are solid surfaces that don't allow water to penetrate, forcing it to run off. ..."

Actually Now Thinking About It Aquifer Is Part Of These Definitions.

You See A Body Of Permeable Rock Which Can Contain Or Transmit Ground Water Is Called, "Aquifer. ..."

We Have That In-Common But With Different Answer Choices?

So My B Is Like Your D.

The Others Are In-Conclusive

So Out Of Your Answers Choices It's

And For My Answer Choices It's

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
