What element is NOT found in nature with 161 neutrons in period 7?
This element is dubnium, the isotope Db-266.
Moisture content in dry basis convert to wet basis?
wb = db/(db+100)
How does this relate to the maximum permissible dose?
You cannot measure exactly the sound pressure level of the noise. It will change a bit. You cannot decide the allowable sound pressure level exactly on the minute. It depeds on the listening person. Some are more sensitive and some are less. "Permitted Exposure Time Guidelines - SPL" Sound pressure level Lp and permissible exposure time t: 115 dB = 0.46875 minutes (~30 sec) 112 dB = 0.9375 minutes (~1 min) 109 dB = 1.875 minutes (< 2 min) 106 dB = 3.75 minutes (< 4 min) 103 dB = 7.5 minutes 100 dB = 15 minutes 97 dB = 30 minutes 94 dB = 1 hour XXX 91 dB = 2 hours 88 dB = 4 hours 85 dB = 8 hours 82 dB = 16 hours Lower dBs are said to be harmless Accepted standards for recommended permissible exposure time for continuous time weighted average noise, according to NIOSH (National Institute for Occupational Safety and Health) and CDC (Centers for Disease Control and Prevention) in 2002. For every 3 dBs over 85dB, the permissible exposure time before possible damage can occur is cut in half.

How many dB of attenuation translates into 50 percent of the voltage being lost to attenuation?
db=20log(V1/V2) or 10log(P1/P2) Example: db=20log (100/50) db=20log(2) db=20*.3010 db=6.02

25dB equal to how many watts?
That depends on you. If you want, you can say 1 watt should be 0 dB.
Normal speech measures 60 dB A busy street measures 70 dB How many times louder is the busy street than normal speech?
70 dB is 10 times louder than 60 dB.
How many time more is the orchestra than the soloist if the orchestra has a sound intensity of 90 db and the soloist has a sound intensity of 70 db?
(90 dB - 70 dB) = 20 dB = 100 times as much sound power.(100 times 'as much' = 99 times 'more')
Compared to a close whisper at 20 dB. How many times more intense is a normal conversation at 60 dB?
10,000
