1

What is the reduction in atomic mass and atomic number when an element emits an alpha particle?

Atomic mass will reduce by 4, atomic number will reduce by 2

2

Difference between the highest and lowest values in a data set?

Range

3

The rate of convective heat transfer can be calculated as which of the following?

Q= hA (Ts-Tb)

4

Contracted from ingestion, inhalation, or contact with infected animals, cuts and scratches

Common in meat packing plants

Brucellosis

5

Class of laser that has an output power of 500 mW, enough to cause permanent eye damage)

Class 3 (have an output power up to 500mW)

6

What does the equation VP (duct velocity pressure) + he (overall hood entry loss) calculate?

Static pressure of the hood

7

Used to calculate the significance of observed differences between the means of two samples

The t-test

(Can also be used to determine if there is a difference between two population parameters)

8

What does anhydrous mean?

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...

Protons are positively charged
Neutrons have a neutral charge
Electrons are negatively charged

18

Formula for lifting index:

LI= object weight/ recommended weight limit

19

What is the constant ratio of gravity?

9.8 m/s 2squared

20

How many feet are in one meter?

3.281

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.

30

How many feet in a mile?

5280 ft = 1 mile
