Back 9

represents the poull that the Earth's gravity has on an object

Mass (definition)

Back 10

amount of matter an object contains

Front 11

Two ways a wave travels

Back 11

Longitiudinal & Tranverse

Front 12

Describe longitiudinal (wave travel)

Back 12

back and forth motion
same direction as the medium

Front 13

Describe transverse (wave travel)

Back 13

up and down motion
perpendicular direction as the medium

Front 14

Work (formula)

Back 14

force X distance

Front 15

What determines pitch & loudness? (sound wave)

Back 15

pitch - wavelength
loudness - amplitude

Front 16

In a light wave, amplitude is related to _________.

Back 16

brightness

Front 17

Explain the Doppler Effect.

Back 17

When an object is moving toward another object it is compressing the wave (blue shift). When an object is moving away from another object the wave is being stretched (red shift).

Front 18

What are the 3 types of radioactive decay?

Back 18

1. Alpha
2. Beta
3. Gamma

Front 19

Describe Alpha Decay.

Back 19

the loss of 2p + 2n = He
The element changes to 2 down of the periodic table.

Front 20

Describe Beta Decay.

Back 20

-n = p + e (+ neutrino).
The element changes to 1 up on the periodic table.

Front 21

Describe Gamma Decay.

Back 21

The protons and neutrons are reshuffling to find a more efficient arrangement. The element is the same but the engery is less.

Front 22

Operation of the CT scanner.

Back 22

The patient is on the x-axis while the scanner works in a sprial, moving on 2 axis' at a time.

Front 23

Laws of Thermodynamics:
1st Law

Back 23

neither matter nor energy can be created or destroyed.

Front 24

Laws of Thermodynamics:
2nd Law

Back 24

Law of Increased Entrophy. When useable engery gets used it becomes unuseable. Once engergy is unuseable it cannot become useable again. An increase in unuseable engery is an increase in entropy.

Front 25

Law of Thermodynamics:
3rd Law

Back 25

refers to absoulte zero (0 degress Kelvin). However, nothing can reach absolute zero due to the 2nd Law of Thermodynamics.

Front 26

Areas most suseptible to radition.

Back 26

lens of eye, skin, GI tract (if ingested), reproductive organs

Front 27

Fission

Back 27

nucleus splits apart with strong force energy released (heavier than Fe)

Front 28

Fusion

Back 28

molecules join together (lighter than Fe)

Isotope

Back 29

varying number of neutrons within an element

Front 30

Half-life

Back 30

The amount of time it takes for half of the isotopes to revert back to their most common form; e.g. C14 to C12

Front 31

Describe Gamma Decay.

Back 31

The protons and neutrons are reshuffling to find a more efficient arrangement. The element is the same but the engery is less.

Front 32
