Containing no water
9
Defined as the flow of electrical charge or the rate of electrical charge
Current
10
What is the Ideal Gas Law?
All internal energy is in kinetic energy form and any change causes a change in temperature
11
Plus or minus one standard deviation from the mean encompasses what percentage of a data set?
Or
Ones standard deviation is equal to?
68% of the data set
12
When two noise sources with identical decimal levels are side by side, how do you calculate the sum of the sound levels?
Apply 3 dB as a doubling effect (add 3 dB)
13
What is formula for PEL of Noise?
T= 8/2(L-90/5)exp
14
Contracted by entrance breaks in the skin from penetrating or crushing trauma
Common in persons handling jute or contact with manure
Tetanus
15
What is the Combined Gas law?
Combines Charles’ and Boyle’s Laws.
The ratio of the product of pressure and volume and the absolute temperature of a gas is equal to a constant.
16
Examples of Non Contact Forces:
Gravitational
Electrical
Magnetic Forces
17
Charges of atoms...

21
When polonium emits an alpha particle, which of decay product is the result?
Lead
22
The degree to which variables in a data set are spread out
Variance
23
How many samples should be collected in an employee group of 11 or 12
10
24
What type of study involves observation of some subset of a population of items all at the same time, in which groups can be compared at different ages with respect to independent variables
Cross-sectional studies
25
Contracted by inhalation or contact with lesions
Common in silica workers, people exposed to heat and organic dusts, medical employees, animal caretakers
Tuberculosis
26
Can be described as the number of scores that are free to vary
Degrees of freedom
27
Formula for Impedence
I=V/A
Voltage / Amperage
28
Under what conditions is the following equation used to measure Wet Bulb Globe Temperature
0.7WB + 0.2GT + 0.1DB
Outdoors w/ a solar load
29
What is Boyles Law?
States that when pressure exerted by a gas is reduced, the volume increases
At a constant TEMPERATURE, a fixed mass of gas occupies a volume that is inversely proportional to the pressure exerted on it.
