100% Verified Answers
Question:
properties of a nucleus
Answer:
protons, neutrons, held together with the 'strong force', nucleus gives atom its mass
Question:
atomic number
Answer:
number of protons in nucleus
- dictates the arrangement of electrons
- defines chemical behavior
- defines the atomic basis of elements
Question:
mass number
Answer:
total protons and neutrons
Question:
isotopes
Answer:
all elements are isotopes
- elements with different numbers of neutrons
- some are highly radioactive; many are slightly radioactive, some are stable and not
radioactive
Question:
what is radioactivity?
Answer:
,the spontaneous decay of nuclei
- radiation can be electrons, subatomic particles, high energy electromagnetic waves like
x-rays
Question:
Geiger counter
Answer:
can be used to detect radioactivity, typically hand-held
Question:
Gamma counters
Answer:
count gamma particles directly: high energy photons
Question:
liquid scintillation counters
Answer:
look at flashes of light in solutions of fluorescent compounds that amplify the strength of
weak radiation
Question:
Battery
Answer:
Developed by Alessandro Volta
Converts chemical energy to kinetic
Electrical Currents flow through dissimilar metals to make a circuit
Question:
Electric circuit
Answer:
Unbroken path of material carrying electricity.
Source, device, and closed path
Question:
, Ohm's Law
Answer:
IxR=V
Current times resistance equals voltage.
Question:
Definition of Wave
Answer:
traveling distance that carries energy but does not result in the overall displacement of
matter/mass
Question:
Types of waves:
Answer:
V (velocity) as always is delta x / delta t. i.e. (difference in location as a function of
difference in time - same as distance per unit time)
Wavelength = (λ) measured in distance
Frequency = (f ) measured in (cycles) per second; cycles/s or s-1. Also measured in Hertz.
The Period = (1/ f ). Literally seconds per cycle; time between waves
Question:
Wavelength measured in...
Answer:
distance by meters
Question:
Velocity is measured in...
Answer:
Delta X divided by Delta T
Meters/Second
Question:
Frequency measured in...
