Answer: are more efficient
Explanation:
7.14 pspicemultisim the switch in the circuit in fig. p 7.14 has been closed for a long time before opening at t
At time t=0, when the switch is closed, the current through the circuit is determined by the voltage source and the resistance in the circuit.
What is circuit?
Electronic components such as resistors, computer chips, capacitors, inductors, and diodes are linked by conductive wires as well as traces that allow electric current to flow between them. It is a specific kind of electrical circuit, and in order for a circuit to be called electronic rather than electrical, there usually needs to be at least each active component present. Signals can be amplified, calculations can be made, and data can be transported from one location to another thanks to the combination of components as well as wires. Although photolithographic techniques on the a laminated substrate (a printed circuit board, or PCB) are now much more common, circuits can still be built from discrete nodes linked by individual wires.
The current will be equal to the voltage source (V) divided by the resistance (R), or V/R. The current will remain constant until the switch is opened at time t. At that point, the current will drop to 0, since the switch will break the circuit.

Exercise 7.1.7: Car Inventory Spoints Let's Go A car company wants to keep a list of all the cars that they have in stock. The company has created a Car class that stores important information about each of their cars. Initialize an ArrayList called inventory that stores each Car that the company has in stock. Status: Not Submitted 7.1.7: Car Inventory Save Submit + Continue iii FILES о со Ол еш мн import java.util.ArrayList; 2 public class CarTracker 3- { public static void main(String[] args) 5 { 6 //Initialize your ArrayList here: 7 } CarTracker.java Car.java Status: Not Submitted 7.17: Car Inventory Save Submit + Continue !!! 2-{ FILES 1 public class Car 3 String name; String model; 5 int cost; public Car (String name, String model, int cost) { this.name 10 this.model = model; this.cost = cost; 12 } CarTracker.java Car.java 6 7 8- 9 = name; 11 13
Answer: To initialize an ArrayList called inventory that stores Car objects in Java, you can use the following code:
import java.util.ArrayList;
public class CarTracker
{
public static void main(String[] args)
{
// Initialize your ArrayList here:
ArrayList<Car> inventory = new ArrayList<>();
}
}
The ArrayList is initialized using the ArrayList<Car> syntax, where Car is the type of objects that will be stored in the ArrayList. The ArrayList is then instantiated using the new ArrayList<>() syntax. You can then add Car objects to the ArrayList using the add method. For example, the following code adds a Car object with the name "Ford", model "Fiesta", and cost $15,000 to the inventory ArrayList:
// Add a Car object to the inventory ArrayList
Car car1 = new Car("Ford", "Fiesta", 15000);
inventory.add(car1);
You can add as many Car objects to the inventory ArrayList as you need. To retrieve a Car object from the ArrayList, you can use the get method and specify the index of the Car object you want to retrieve. For example, the following code retrieves the first Car object in the inventory ArrayList:
// Get the first Car object in the inventory ArrayList
Car car = inventory.get(0);
You can then access the fields of the Car object using the dot notation, as shown in the following code:
// Print the name, model, and cost of the Car object
System.out.println("Name: " + car.name);
System.out.println("Model: " + car.model);
System.out.println("Cost: $" + car.cost);
This code would output the name, model, and cost of the Car object.

Electronic rack-and-pinion systems use an electric motor to pump the hydraulic fluid through the hoses. True/False
True, Electric motors are used in electronic rack and pinion systems to push hydraulic fluid through the hoses.
What is hydraulic?
Engineering, chemistry, as well as other applied sciences involving this same mechanical properties and application of liquids are used in hydraulics (from the Greek: Y). Hydraulics, which deals with liquids, is fundamentally the gaseous counterpart of pneumatics. Hydraulics, that also focuses on utilizing the properties of fluids in applied engineering, has its theoretical foundation in fluid mechanics. In its hydraulic systems applications, hydraulics makes use of pressurised liquids to generate, control, and transmit power. Hydraulic topics cover ideas like pipe flow, dam design, fluidics, and fluid control circuitry and are covered in some science and the majority of engineering modules. The vascular system as well as erectile tissue of the human body naturally use hydraulic principles.

An insurance company offers its policyholders a number of different premium payment options. For a randomly selected policyholder, let X = the number of months between successive payments. The cdf of X is as follows...
The cdf of X is as a) X has a pmf of x p(x) (x), 1 0.33, 3 0.11, 4 0.04 6 0.38,12 0.14
b) P(3≤X≤6)=0.53, P(X≥4)=0.56
We must determine the pmf of x.
The fact that
F(x)=P(X≤ x)
F(0)=P(X 0)=P(X= 0)=P(X=f) (0)
F(1) = P(X 1) = P(X=0) + P(X=1) = f(0) + f (1)
because f(0)=F(0),
f(1)=F(1)-F(0)
F(2)=P(X2)=P(X=0), P(X=1), P(X=2), F(1), and f (2)
f(2)=F(2)-F(1)
Thus, it is safe to say
f(3)=F(3)-F(2)
f(4)=F(4)-F(3)
f(6)=F(6)-F(5)
f(12)=F(12)-F(11).
Given to us is that
F(0) = 0, F(1) = 0, F(2) = 0, F(3) = 0, F(4) = 0, F(5) = 0, F(6) = 0, F(7) = 0, F(8) = 0, F(9) = 0, F(10) = 0, F(11) = 0, F(12) = 1.
Finding f(1), f(3), f(4), f(6), and f is required (12).
f(1)=F(1)-F(0)=0.33-0=0.33
f(3)=F(3)-F(2)=0.44-0.33=0.11
f(4)=F(4)-F(3)=0.48-0.44=0.04
f(6)=F(6)-F(5)=0.86-0.48=0.38
f(12)=F(12)-F(11)=1-0.86=0.14
X has a pmf of
x p(x) (x)
1 0.33
3 0.11
4 0.04
6 0.38
12 0.14
P(3≤X≤6)=?
We understand that P(aXb)=F(b)-F. (a)
P(3≤X≤6)=P(2<X≤6)=F(6)-F(2)=0.86-0.33=0.53
P(3≤X≤6)=0.53
P(X≥4)=?
P(X≥4)=1-P(X<4)=1-P(X≤3)=1-F(3)=1-0.44=0.56
P(X≥4)=0.56

____streams are not connected to groundwater systems and only flow after precipitation events.
Ephemeral streams only flow after precipitation events and are not connected to groundwater systems.
Ephemeral streams are waterways that don't have a distinct course and only flow when it rains. These characteristics frequently manifest as dry terrain without recent rainfall and are common in arid or semi-arid locations. Dry streambeds are referred to as ephemeral streams, and they flow as rivers or streams when it rains. In times of drought, the dried-up streambeds accumulate layers of fertile soil. In the event of rain, ephemeral streams transport this dirt downstream where it is deposited along the riverbank, refilling the region with silt. The majority of streams in dry or semi-arid areas, like Arizona or New Mexico, are often ephemeral streams. Moving downslope, surface runoff collects in low spots and creates little stream channels.
