AP board question.... An urban planner is designing a new urban housing development in a currently rural area near an existing city. The urban development will have five 10-story apartment buildings, two basketball courts, a playground with permeable foam pavers, a 10-acre green space with a small man-made pond, one 5-story parking deck, and direct access to the mass transit train line. Which of the following aspects in the design for this new urban development would most likely have the greatest negative environmental impact?

Answer:

Core analysis reports often show depths broken into increments of 1/2 feet because it provides a more detailed and accurate representation of the geologic layers present in the subsurface. By breaking the depth into smaller increments, geologists can more accurately depict the thickness and distribution of different geologic units and identify any changes or variations within those units. This can be especially important in cases where the geology is complex or there are small variations in the subsurface that could have significant impacts on the exploration or development of a resource.

In some cases, core analysis reports may show depths in whole feet rather than 1/2 feet. This is usually done when the geology is relatively simple and there are no significant variations within the geologic units being analyzed. In these cases, showing the depths in whole feet may be sufficient to accurately represent the geology and meet the needs of the project.

Ultimately, the decision to show depths in 1/2 feet or whole feet will depend on the specific needs of the project and the complexity of the geology being analyzed. Both approaches can be useful for different purposes and it is important to choose the one that is most appropriate for the task at hand.

Below is the solution of the voltage and current on the secondary side when an ideal transformer has 20 turns on its primary side and 90 turns on its secondary side.

Step-by-step solution -

Given,

[tex]V_{P} = 200V\\N_{P} = 20\\N_{S} = 90[/tex]

For Transformer -

[tex]\frac{V_{P}} {V_{S}} = \frac{N_{P}} {N_{S}}[/tex]

[tex]\frac{200} {V_{S}} = \frac{20} {90}[/tex]

[tex]V_{S} = \frac{1800}{2} = 900 V[/tex]

For Ideal transformer ,

[tex]P_{OUT} = P_{IN}}[/tex]

200 x 50 = 900 x  [tex]I_{S}[/tex]

[tex]I_{S}[/tex] = 100/9 A.

True. The dispersion of contaminants in a room can be modeled using a large number of Lagrangian particles in a random process. In this approach, the movement of each particle is tracked as it moves through the room, and the concentration of contaminants at different points in the room is calculated based on the distribution of the particles. This allows researchers to understand how the contaminants will spread throughout the room and how long they will remain in the air.

Lagrangian particle modeling is a useful tool for predicting the dispersion of contaminants in indoor environments, as it takes into account the influence of the room's geometry and the flow of air within the space. It can be used to evaluate the effectiveness of ventilation systems and to identify potential areas of high contaminant concentrations that may pose a risk to the occupants of the space.

Since, a synchronizer matches gear speed with shaft speed.It is used for shifting gears while driving. The synchronizer works like a friction clutch, decelerating or accelerating the input shaft to match the speed of the next gear.

What is a synchronizer?

A synchronizer matches the rotational speed of the desired gear to the rotational speed of the output shaft. The gears are constantly meshing.

The shift fork moves the synchronizer's sleeve to lock the spinning gear to the shaft. It makes use of a blocking ring made of brass or soft metal to make contact with the gear's dog teeth.

These brass rings are inexpensive and wear over time, becoming rounded. When the teeth appear worn or rounded, they should be replaced.

Note that the lighting load on a 120v circuit for six 100w incandescent lights and four fluorescent fixtures with a ballast rating of 1.5a, all operating continuously for 8 hours per day is: 10,560 Watts.

A building's lighting loads are sometimes referred to in terms of "Lighting Power Density," which is measured in watts per square foot or square meter.

It is to be noted that a single calculation is used to compute lighting load:

W=VA.

Where

W = Watts

V = Volts; and

A = Amps

To determine the total wattage for the fluorescent fixtures we say:

4 fixtures x 1.5 amps x 120 volts = 720 watts

Next, we add the wattages for the incandescent lights and fluorescent fixtures to get the total wattage for the circuit. That is:

(6 x 100watts) + 720 watts
= 600 watts + 720 watts

= 1,320 watts

Thus the Load is 1,320 watts.

If all lighting will operate continuously for 8 hours/day, then:

Daily energy consumption will be:

1320 x 8

= 10,560 Watts.

Ohm's law states that the "current in a circuit is equal to the voltage applied to the circuit divided by the total resistance of the circuit".

To solve this problem, we need to first determine the total resistance of the two resistive heating elements in the circuit.

Since the heating elements are connected in series, their resistances add up, so the total resistance of the circuit is

⇒ 2 x 2.8 kW / 250 V = 11.2 kW / 250 V = 0.0448 kW / V.

As per Ohm's law, the current in the circuit would be
