Given that,
Mass of water, m = 5 kg
The temperature increases from 20℃ to 40℃.
Specific heat capacity of water is 4200 J kg⁻¹ k⁻¹
To find,
Heat energy required to raise the temperature.
Solution,
The formula for the heat energy required to raise the temperature is given by :

So, the heat energy required is 420 kJ.

Explanation:
public class RecursiveCalls {
public static void backwardsAlphabet(char currLetter) {
if (currLetter == 'a') {
System.out.println(currLetter);
}
else {
System.out.print(currLetter + " ");
backwardsAlphabet(--currLetter);
}
return;
}
public static void main (String [] args) {
char startingLetter = '-';
startingLetter = 'z';
// Your solution goes here
backwardsAlphabet(startingLetter);
return;
}
}

Explanation:
Kindly find the explanation attached
=sum(1+1) it's a simple formula and won't change from any cells. Another you can do is to put a value in a specific cell, let's say, C3. Then have a formula that says, =sum(C3+2). But if you REALLY wanna impress someone - put a value in A1 - anything at all. Then put this formula in any other cell you want. If you change cells, you get a different answer. If you change the # in A1, you get different answers, all thanks to the RANDom function. =SUM((RAND()*100)+A1)
Answer: try to restart It
Explanation:Random reboots can happen because of problems with the firmware, but can also be due to some app you installed that is making the system unstable, or perhaps some bad bit of data that is in the system cache. A corrupt SD card can also cause problems.
