how can robots help us with online learning? 3 reasons please thank u :)​

Answers

Answer:

The use of robots increases the practicality of online education, such that the difference between in person attendance and online learning is minimized

In elementary school, robots can help deliver teaching materials in a class like setting, to students  who are unable to attend classes due to their current situation

In high school, simulators can give driving (and flying) lessons to would be drivers, without the exposure of the students to risk

Robots in higher education, such as medicine, can be used to carry out operational procedures with students where, there are no subjects to perform the surgical procedure on

The use of simulators makes possible training in disaster and crisis management

Answer:

The "Creeper system," the first computer virus, was an experimental self-replicating virus released in 1971. It was filling up the hard disk to the point that a computer could no longer function. BBN technology in the United States produced this virus. When the Creeper virus infects a computer, it causes it to output a file. It will then cease to function while it searches for another TENEX system. It creates a connection with the machine in question, and so on. Its last payload or impact when it's finished with a system is to display its message.

Management reminds the systems administrators about the data sanitization and disposal policy. What policy items are applicable for these IT systems, prior to donating to the schools

Answers

The "DoD Standard" is a term used during the data sanitizing industry and refers to DoD 5220.22-M, and the further discussion can be defined as follows:

The simplest ways are being used to help eliminate the previously stored data, by deleting hard disc storage facilities with the same data wherever that used a sequence of all zeros.The sparging eliminates statistics to entirely delete the gravitational flux from electronic media. Hard drives as well as other data storage devices, for example, computer tapes, retain magnetic data. It could no longer be seen as storage after a disk is degaussed.

Assume the existence of a Building class. Define a derived class, ApartmentBuilding that contains four (4) data members: an integer named numFloors, an integer named unitsPerFloor, a boolean named hasElevator, and a boolean named hasCentralAir. There is a constructor containing parameters for the initialization of the above variables (in the same order as they appear above). There are also two function: the first, getTotalUnits, accepts no parameters and returns the total number of units in the building; the second, isLuxuryBuilding accepts no parameters and returns true if the building has central air, an elevator and 2 or less units per floor.

Answers

Answer:

Explanation:

The following code is written in Java. The class ApartmentBuilding extends the assumed class of Building but does not call any of its methods since we do not have access to it. The ApartmentBuilding class contains all of the variables listed, as well as constructor and methods, including getter and setter methods for each variable. A test case for the class is provided in the image below with it's output.

class ApartmentBuilding extends Building {

   int numFloors, unitsPerFloor;

   boolean hasElevator, hasCentralAir;

   public ApartmentBuilding(int numFloors, int unitsPerFloor, boolean hasElevator, boolean hasCentralAir) {

       this.numFloors = numFloors;

       this.unitsPerFloor = unitsPerFloor;

       this.hasElevator = hasElevator;

       this.hasCentralAir = hasCentralAir;

   }

   public int getTotalUnits() {

       int total = this.numFloors * this.unitsPerFloor;

       return total;

   }

   public boolean isLuxuryBuilding() {

       if ((this.hasCentralAir == true) && (this.hasElevator == true) && (this.unitsPerFloor <= 2)) {

           return true;

       } else {

           return false;

       }

   }

   public int getNumFloors() {

       return numFloors;

   }

   public void setNumFloors(int numFloors) {

       this.numFloors = numFloors;

   }

   public int getUnitsPerFloor() {

       return unitsPerFloor;

   }

   public void setUnitsPerFloor(int unitsPerFloor) {

       this.unitsPerFloor = unitsPerFloor;

   }

Draw a circuit with a 12-volt battery, a 100 ohms resistor in series, and two resistors (each of value 200 ohms) in parallel. What is the total resistance of the circuit?

Answers

Answer:

200 Ω

Explanation:

Hi there!

Please see below for the circuit diagram.

1) Find the total resistance of the resistors in parallel

Total resistance in parallel equation: [tex]\frac{1}{R_T} = \frac{1}{R_1} +\frac{1}{R_2}[/tex]

Both the resistors measure 200 Ω. Plug these into the equation as R₁ and R₂:

[tex]\frac{1}{R_T} = \frac{1}{200} +\frac{1}{200}\\\frac{1}{R_T} = \frac{1}{100}\\R_T=100[/tex]

Therefore, the total resistance of the resistors in parallel is 100 Ω.

2) Find the total resistance of the circuit

Now, to find the total resistance of the circuit, we must add the 100 Ω we just solved for and the 100 Ω for the other resistor placed in series:

100 Ω + 100 Ω = 200 Ω

Therefore, the total resistance of the circuit is 200 Ω.

I hope this helps!

DMT — or N, N-dimethyltryptamine in medical talk — is a hallucinogenic tryptamine drug. Sometimes referred to as Dimitri, this drug produces effects similar to those of psychedelics, like LSD and magic mushrooms. Other names for it include: fantasia.

Explanation:

Answer:

DMT, abbreviation of Dimethyltryptamine, powerful, naturally occurring hallucinogenic compound structurally related to the drug LSD (lysergic acid diethylamide). DMT blocks the action of serotonin (a transmitter of nerve impulses) in brain tissue. It is inactive when taken by mouth and produces effects only when injected, sniffed, or smoked. The hallucinatory action

Major plant genera containing DMT include Phalaris, Delosperma, Acacia, Desmodium, Mimosa, Virola, and Psychotria, but DMT has been found even in apparently innocuous sources, such as leaves of citrus plants (Servillo et al., 2012), and in the leaves, seeds, and inner bark of mimosa tenuiflora

cual es el procedimientos para asistir en el transporte publico a personas discapacitadas

Answers

Answer:

Una discapacidad física o motora en una o más partes del cuerpo obstaculiza las acciones y / o movimientos de la persona con discapacidad. La discapacidad puede surgir porque las partes del cuerpo no han crecido completamente o están dañadas (anomalías físicas) o porque las funciones físicas están alteradas (anomalías funcionales).

En la mayoría de los casos, se proporciona una ayuda a las personas con discapacidades físicas graves para que puedan desenvolverse más fácilmente en la sociedad. Alguien con una discapacidad motora severa en las piernas a menudo usa una silla de ruedas. Las personas con una discapacidad motora de las manos (pérdida de la motricidad fina) o de los brazos pueden compensar esto con un manipulador o ayudas especializadas en tareas, como un dispositivo para comer o un dispositivo para girar las hojas.

Así, todos estos elementos deben ser posibles de ser insertados en los medios de transporte público como forma de ayudar a estas personas a trasladarse por estos medios, es decir, los autobuses, trenes, etc., deben estar adaptados para poder recibir allí a pasajeros en sillas de ruedas o con necesidades motoras especiales.

B: Shift your transmission to neutral

C: Try to re-start; if unable, stop off road, using four-way flashers

D: All of the above

Answers

Answer:

D

Explanation:

All of the above should you do if your engine stalls while you are driving. Thus option D is correct.

What is driving?

Driving, which includes operating and moving a vehicle in a controlled manner, includes using a car, scooter, truck, vehicle, or scooter. Drivers must abide by the local highway and traffic rules in order to be allowed to drive on city roads, which is contingent upon a number of requirements being completed.

In most situations, you'll lose auto steering whenever the engine shuts off, making it challenging to spin the wheel, as well as power brakes will shortly follow.

Although it takes significantly more pressure, you could still steer but instead, stop. Put the gearshift in neutral. If you can't restart, stop off the road and use your 4 blinkers. Therefore, option D is the correct option.
