An artesian system is present when groundwater __________.

ahrayia [7]

<h2>Answer: under pressure rises above the aquifer level</h2>

Explanation:

An artesian system is one that connects with an accumulation of water (aquifer) whose surface or level is above the surface of the system or well.

In other words, the upper limit of the aquifer is higher than the opening through which the liquid flows in the artesian well. This has the advantage that the water spreads without needing to be pumped.

It should be noted that its name comes from the region of <u>Artois</u>, France, where in 1126 the oldest well in Europe was drilled with these characteristics.

Therefore:

<h2>An artesian system is present when groundwater <u>under pressure rises above the aquifer level.</u></h2>

1. Calculate the resistance of a 12v, 20-amp circuit.

Elis [28]

Answer:

R = 0.6 ohms

Explanation:

We have,

Voltage of the circuit is 12 V

Current flowing in the circuit is 20 A

It is required to find the resistance of the circuit. Ohm'slaw gives the relationship between voltage, current and resistance. It is given by :

$V=IR$

R = resistance

$R=\dfrac{V}{I}\\\\R=\dfrac{12}{20}\\\\R=0.6\ \Omega$

so, the resistance of the circuit is 0.6 ohms.

When riding a 10-speed bicycle up a hill, a cyclist shifts the chain to a larger-diameter gear attached to the back wheel. Why i

dimaraw [331]

To solve this problem we will use the concepts of the moment of rotational inertia, angular acceleration and the expression of angular velocity.

The rotational inertia is expressed as follows:

$I = \sum mr^2$

Here,

m = Mass of the object

r = Distance from the rotational axis

The rotational acceleration in terms of translational acceleration is

$\alpha = \frac{a}{R}$

Here,

a = Acceleration

R = Radius of the circular path of the object

The expression for the rotational speed of the object is

$\omega = \frac{\Delta \theta}{\Delta t}$

Here,

$\Delta \theta$ is the angular displacement of the object

The explanation by which when climbing a mountain uphill is changed to a larger pinion, is because it produces a greater torque but it is necessary to make more pedaling to be able to travel the same distance. Basically every turn results in less rotations of the rear wheel. Said energy that was previously used to move the rotation of the wheel is now distributed in more turns of the pedal. Therefore option a and c are correct.

This would indicate that the correct option is D.

Your bedroom has a rectangular shape, and you want to measure its area. You use a tape that is precise to 0.001 and find that th

Anarel [89]

Answer:

(a) $17.0 m^{2}$

(b) $31.4 m^{2}$

Explanation:

(a)

The result obtained by multiplying two values which are having different precision has to express in the precision of the least precise number. So among the given values 4.79 is the least precise value; hence round off the result to 3 significant figures. For a rectangular room, area is a product of length and width, here, l is length and b is width/breadth

$Area=lb=4.79*3.547=16.9901\approx 17.0 m^{2}$

(b)

Following the same rules mentioned in part a of the question

For circular shaped bedroom, area $A={\pi (d/2)^{2}}$

$A=\pi\times (6.32/2)^{2}=31.37 m^{2}\approx 31.4 m^{2}$

The diameter of the circular room is 6.32, this is the least precise value used to calculate the area, so round off the final result to 3 significant figures

If Joe rides south on his bicycle in a straight line for 15 min with a average speed of 12.5 Km/h, how far has he ridden?

Olegator [25]

Using Dimensional analysis
15min/1·1hr/60min
15/1·1hr/60=15/60hr
.25hr
.25hr·12.5Km/h=3.125Km
