Explanation:

A situation in which a teen might improve can be in a school setting where the student notices that there is a lack of recycling infrastructure and an increase in waste. The student can come up with a plan to set up recycling bins around the campus, create an educational campaign to encourage their classmates to recycle, and coordinate efforts with the school administrators to ensure the waste is collected and disposed of properly. Through this initiative, the student can make a positive impact on the school by reducing its environmental footprint and setting an example for others to follow. The teen's leadership and civic engagement can inspire a sense of responsibility and environmental awareness in their school community.

Answer:

The amount of money saved is $22,075.2

Explanation:

The solar voltaic energy in Phoenix, S\(_E\) = 6,720 Wh/m²/day

The area on the roof available for solar panels, A = 500 m²

The percentage of the energy received by the solar panels converted into electricity, η = 15% = 0.15

The cost of electricity, C = $0.12/kWh

The number of days in a year, t = 365 days

Therefore, the maximum area covered by the solar panel = A = 500 m²

The total solar photovoltaic energy received by the solar panels, 'E', in a year is given as follows;

E = S\(_E\) × A × t

By plugging in the values of the variables, we get;

E = 6,720 Wh/m²/day × 500 m² × 365 days = 1,226,400,000 Wh

The electrical energy generated, \(E_e\) = η × E

∴ \(E_e\) = 0.15 × 1,226,400,000 Wh = 183960000 Wh = 183,960 kWh

The amount of money saved = The cost of electricity generated = C × \(E_e\)

C × \(E_e\) = $0.12/kWh × 183,960 kWh = $22,075.2

∴ The amount of money saved = C × \(E_e\) = $22,075.2

The current through R2 is 0.3 A and the voltage across R2 is 15 V. The current through R3 is 0.1 A, and the voltage across R3 is 5 V.

Generally, To find the current through R2 and R3 and the voltage across them, you can use Ohm's law and Kirchhoff's laws.

Ohm's law states that the current through a resistor is directly proportional to the voltage across it, with the proportionality constant being the resistance. Mathematically, this can be written as:

I = V / R

Where I is the current, V is the voltage, and R is the resistance.

Kirchhoff's laws can also be used to solve for the currents and voltages in a circuit. Kirchhoff's current law states that the sum of all the currents entering a node (a point where three or more branches meet) must be equal to the sum of all the currents leaving the node. Kirchhoff's voltage law states that the sum of the voltage drops around a loop must be zero.

Using these laws, you can set up a system of equations to solve for the unknowns in the circuit.

For the given circuit, you can start by labeling the currents and voltages as shown:

I1 = current through R1 I2 = current through R2 I3 = current through R3

V1 = voltage across R1 V2 = voltage across R2 V3 = voltage across R3

Then, you can use Ohm's law to write equations for the voltages across each resistor in terms of the currents and resistances:

V1 = I1 * R1 V2 = I2 * R2 V3 = I3 * R3

You can also use Kirchhoff's current law to write an equation for the current at the top node:

I1 + I2 + I3 = 0

And Kirchhoff's voltage law to write an equation for the voltage around the loop:

V1 + V2 + V3 = 0

Substituting the expressions for V1, V2, and V3 from Ohm's law into the equations from Kirchhoff's laws, you get a system of three equations with three unknowns:

I1 * R1 + I2 * R2 + I3 * R3 = 0 I1 + I2 + I3 = 0

You can then solve this system of equations to find the values of I1, I2, and I3, and then use Ohm's law to find the voltages V1, V2, and V3.

Solving this system of equations, you find that:

I1 = -0.2 A I2 = 0.3 A I3 = 0.1 A

V1 = -6 V V2 = 15 V V3 = 5 V

Answer:

C. \(1.90\leq x \leq 2.10\)

Explanation:

The question states that x has is value in between and including 1.9 and 2.1. So the number is greater than or equal to 1.9 but less than or equal to 2.1.

In option A \(x\geq 2.1\) this means that the value of x is greater than or equal to 2.1 which does not satisfy the condition mentioned in the question

In option D \(x\) is greater than or equal to 2.1 but less than or equal to 1.9 which does not satisfy the condition mentioned in the question.

In option C \(x\) is greater than or equal to 1.9 and less than or equal to 2.1 which does satisfy the condition mentioned in the question.

So, option C is correct.

Define the problem do it research develop your research

Answer:

to find a solution to a problem.

Explanation:

The engineering design process, by definition, is a series of steps that engineers use to find a solution to a problem. These steps include: defining the problem, brainstorming solutions, designing and building a prototype of the solution, testing the solution, and improving it.

Answer:

The first step of the problem solving process is to identify and define the problem. The second step, which is to analyze the problem, involves gathering information, sorting through relevant and irrelevant information, and evaluating the source of the problem by asking the Five W's: who, what, where, when, and why.

The magnetic field at a point P whose coordinates are P (0, 0, d) ​is 2μi/3πd

A magnetic field is the region where the effect of a magnetic force is felt.

First, we need to find the magnetic field due to each wire, then we find the resultant magnetic field at P

The magnitude of the magnetic field on each wire is given by B = μi/2πr where

Given that

B₁ = μ(i/3)/2πd

= μi/6πd

Given that

B₂ = μ(i/3)/2πd

= -μi/6πd

B' = B₁ + B₂

= μi/6πd - μi/6πd

= 0

Given that

B₃ = μ(i/3)/2πd

= μi/6πd

Given that

B₄ = μi//2πd

B" = B + B

= μi/6πd + μi/2πd

= μ(i + 3i)/6πd

= μ4i/6πd

= 2μi/3πd

So, the net magnetic field at P is B = B' + B"

Since

B = B' + B"

= 0 + B

= B"

= 2μi/3πd

So, the magnetic field at a point P whose coordinates are P (0, 0, d) ​is 2μi/3πd

Your answer would be "C" Enters a reservoir !! :D

Explanation:

did it on EDGE 2021 got it right , here is an exact exerpt from EDGE \/ \/ \/

Open Fluid Systems

However, if the fluid leaves the actuator to enter a reservoir, and then fresh fluid leaves the reservoir to enter the pump, then this is an open-loop fluid system. Since the fluid enters a reservoir, the open-loop fluid system generates less heat and is often preferred by engineers over the closed-loop fluid system. Additionally, open-loop systems have no internal pressure when the motor or actuator is idle. Therefore, the motor or actuator must be engaged to create the internal pressure needed for fluid power systems.

In open fluid systems the fluid only flows through the system one time. Civil engineers who work with city water systems analyze open fluid systems.""
