The sound of a man shouting at the top of his lungs from a rather large distance away from your ear has loudness of only 20 deci

bels. What would be the decibel level of four men shouting at the top of their (equally powerful) lungs from the same distance away from your ear? Assume that there is no interference from superposed waves and round off your answer to the nearest integer. 1. 160 dB 2. 80 dB 3. 60 dB 4. 10 dB 5. 14 dB 6. 6 dB 7. 20 dB 8. 40 dB

Answer:

26dB

Explanation:

The decibel level β is a calculated by 10log (I/Io)

Where I and Io represent sound intensity

From the question, there's no interference. So

Where I = 4Io (because there are 4 men shouting), so the intensity will be 4 times larger.

β = 10log (I/Io)

β = 10log (4Io/Io)

β = 10log 4

β = 6.020599913279623

β = 6 ---- Approximated

The decibel level = 20 + 6.020599913279623

Decibel Level = 26.020599913279623

Decibel level =26dB --- Approximated

1. True or False: A low BAL will always cause a hangover. True False
liberstina [14]
1. I am completely sure that this statement is false. Because HIGH BAL will ALWAYS cause a hangover. BAL is a blood-alcohol level, which means a level of alcohol intoxication. High BAL can be produced drinks with congeners, like whiskey, tequila and cognac.

2.  According to its definition, complete statement should look like this: perception is what gives meaning to our senses. Perception is our ability to see or feel something. It helps us understand something or to become aware of something.

3. I am completely sure that judgment <span>is the first ability affected by alcohol. High blood-alcohol level badly affects your judgement, coordination, vision and memory. Drinking alcohol increases your risk for life threatening diseases. 

4. If my memory serves me well, the statement should be completed like this: </span><span>Alcohol, or any other drug which reduces the supply of oxygen in the bloodstream, can impair the sensitivity of the cones which, in turn r</span>educes the visual acuity or sharpness.
5. Hand-eye coordination, walking, and balance, also known as coordination, are adversely affected by alcohol. As I've mentioned it before in question 3 the coordination is badly affected by alcohol.

6. As far as I remember, short-term side effects of alcohol and other drugs include d<span>isrupted sleep. But it depends on an individual. All of the above can be the side effects of alcohol and other drugs. But if you need to choose only one option, than its the first one.

7. I am pretty sure that alcohol can increase fatigue because it's one of the effects of high blood-alcohol level. Driving while fatigued can cause slow reaction time and decreased headlights speed.

8. In my view, the correct answer is: </span>In the case of distance judgment, the brain receives two slightly different images from the two eyes. Brain receives nerve signals produced by encoding this images.

9. I am 100% sure that s<span>peed in addition to the effects of alcohol greatly reduces a driver's vision. Affected by the alcohol, driver's field of view is reduced and speed reduces it even more.

10. I think that this statement is definitely TRUE, because the kidneys are responsible for excreting excess water. </span>
