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:
Hi there Rumanruxi! The error is in the if statement "if(userNum = 2)".
Explanation:
The if statement in this Java code is assigning userNum the value of 2 instead of comparing it with the value of 2. For equals comparison we need to write two equals "==" in the statement as: "if (userNum == 2)". This will return true if userNum is 2 otherwise it will return false.
This is in fact false to my knowledge
