Answer:
var movie = {
name: "Avengers Endgame",
director: "Joe Russo",
composer: "Alan Silvestri",
cast: {
"Scarlett Johansson": "Black Widow",
"Chris Evans": "Captain America"
},
roleOf: function (name) {
if (typeof (this.cast[name]) !== 'undefined') {
return this.cast[name];
} else {
return "The actor is not part of this movie";
}
}
};
Explanation:
- Initialize the movie JSON (JavaScript Object Notation) having the name, director, composer and cast properties.
- Define a roleOf: function that has a name parameter.
- Check whether the selected is not equal to undefined and then return that name.
- Otherwise display this message: "The actor is not part of this movie".
Answer:
In a case where electrical current leakage from the circuit occurs, the GFCI would do the following:
1. Sense the current leakage.
2. Trip the circuit.
3. Cut off the electricity.
Electrical current leakage needs to be sensed at once. Without it being detected, it cant be dealt with. The second step consists of tripping the circuit so at to remove the flow of electricity. The third step is to Cut the electricity off so to stop the leakage and be safe.
I hope the answer is helpful.
Thanks.
Answer:
The correct answer for the given question is option(B) i.e "database system"
Explanation:
Database is the collection of interrelated data .Database system is an organization of components that define and regulate the collection, storage and manage the data.Database system maintain the integrity in the database. Database system provides an interface to the database for information storage and retrieval.
Transaction is the contract between a buyer and a seller to interchange goods or services. it does not regulate the collection store the data so this option is wrong .
Structured data and management system does not store the data that define and regulate the collection in organization. So this option is also wrong
So correct answer is database system.
The resistance is 16 ohm's
V=I x R where V is the voltage, I is the current, and R is the resistance in Ohms
120= 15 x R
R=120/15
R= 8 Ohm's
P=VxV / R
P=120v x 120v / 8 ohms
P= 14400/8
P = 1800 watts
R = V x V/P
R = 14400/900
R = 16 Ohm's
The resistance is 16 ohm's:
I = V/R
I = 120/16
I = 7.5 Amps
Answer:
A DNS Server
Explanation:
DNS (Domain Name Server) is a server or a computer that holds the records of IP addresses on the internet or any network with their associated names of hosts, the job of the DNS is to resolve the domain name to an ip address that corresponds to the requested name everytime there is a request on a particular domain name.
