Answer:
- <u>1,000W</u> (rounded to one significant figure)
Explanation:
I will answer in English.
The question is:
- <em>What is the power of a filament lamp that connects to the 220 V network, knowing that it has a resistance of 50 ohms?</em>
<em />
<h2>Solution</h2>
<em />
<em>Power</em>, <em>voltage</em>, <em>resistance</em>, and current, are related by either of the following equations:
Where:
- R is resistance in ohms (Ω)
- V is voltage in volts (V), and
- I is current in amperes (A)
Since you know the voltage (<em>220V</em>) and the resistance (<em>50Ω</em>), you can use the last equation:
Since the magnitude 50Ω has one significant figure, your answer should be rounded to one significant figure. That is <u>1,000W.</u>
Im going to guess the 2nd one.
The 1st one just shows how trees can make ____ and then goes to water, the sun, then the rain but it CAN be used as one.
The 2nd one seems to explain the best it can show about weather, water, landforms, the sun, and seems like a better one to choose.
Answer:
highest of five numbers in the file
Explanation:
- This code reads the file "some-file.txt" and saves the result in variable "somefile"
- The runs a for loop for a count of 5.
- In each loop it compares the current value of the file with the value of the variable result and if the result is true it updates the value of the variable result.
- At the end of this code the variable result will contain the highest value in the file "some-file.txt" and print it.
Answer:
const MAXNR=150;
let candidates = {};
for(let i=2; i<=MAXNR; i++) {
candidates[i] = true;
}
for(let p=2; p <= MAXNR; p++) {
if (candidates[p]) {
process.stdout.write(`${p} `);
// Now flag all multiples of p as false
i=2;
while(p*i <= MAXNR) {
candidates[p*i] = false;
i++;
}
}
}
