Answer:
69.54
Explanation:
A power ratio of 9000000:1 corresponds to 69.54 dB.
The calculation is presented below:
Formula for calculating Power ratio (db) = 10 * log [P(out)/P(in)]
Since the given ratio is 9000000:1, substituting in the formula gives us 10 * log (9000000/1)
Note that log 9000000 = 6.954
Therefore, 10 * log (9000000/1) = 69.54
Hence the required power ratio in db is 69.54 db.
Answer:
public class TestImport{
public static void main(String[] args) {
String string1 = args[1];
String string2 = args[2];
System.out.println(string1 +" " +string2);
}
}
Explanation:
The solution here is to use string concatenation as has been used in this statement System.out.println(string1 +" " +string2);
When this code is run from the command line and passed atleast three command line arguments for index 0,1,2 respectively, the print statment will return the second string (that is index1) and the third argument(that is index2) with a space in-between the two string.
Answer is: Yes
<u>Explanation:</u>
Word includes a full-screen mode that minimizes the extraneous information (tools, menus, etc.) displayed on the screen. The normal way of switching to full-screen mode is to display the View tab of the ribbon and click Full Screen Reading in the Document Views group. (If you are using Word 2013 or Word 2016 click Read Mode in the Views group.) You can also click the Full Screen Reading view icon (Read Mode view icon Word 2013 and Word 2016) near the right side of the Status bar located at the bottom of the document window. You exit the mode by either clicking the Close button (upper-right corner of the screen) or by pressing Esc.
Answer:
0.127 miles ; 5.458 *10^8 miles
Explanation:
Number of bytes needed to store a page = 2000
Number of pages (Harry Potter's book) = 800
Total memory required to store entire book = (2000 * 800) = 1600000 = 16 * 10^5 bytes
Hence,
1 byte of memory will store : (height of each book / memory size of each book)
= 3 ÷ 16 * 10^5
= 1.875 * 10^-6
For 32 bit memory space :
(1.875 * 10^-6 * 2^32) = 8053.06368 inches
1 inch = 1.578 * 10^-5 mile
8053.06368 inches = 8053.06368 * (1.578 * 10^-5) = 0.1270773448704 miles
= 0.127 miles
For 64 bit memory size :
(1.875 * 10^-6 * (2^64)) = 3.45876 * 10^13 inches
(3.45876 * 10^13) * (1.578 * 10^-5)
= 5.458 *10^8 miles
