THE FINAL SCIENCE PACE OF ALL TIME (Q&B) Flashcards
The four most common types of stresses
stretching
bending
compressing
twisting
the two necessary ingredients of work
force
distance
The six simple machines
wheel and axle lever pulley wedge inclined plane screw
The three methods of heat transfer
conduction
convection
radiation
How an airplane flies
Air travels over the wings at high velocity, creating a region of low pressure. The region of high pressure beneath the wings moves toward the region of low pressure, lifting the plane
The three basic assumptions of the kinetic theory of gases
gas molecules are widely separated
gas molecules move rapidly and freely in all directions
gas molecules frequently undergo elastic collisions with one another and the walls of their container
When light strikes a surface, it may be _________
reflected, absorbed, or transmitted
The three different spectra used by physicists
absorption, continuous, and emission
The energy of electrons emitted by the photoelectric effect is determined by
the color of light
The number of electrons emitted by the photoelectric effect is determined by
the brightness of light
The photoelectric effect (not in checkup but whatever)
the emission of electrons by light falling upon the surface of certain metals
the three laws of static electricity
charged bodies attract uncharged bodies
like charges repel
unlike charges attract
three ways an object can acquire a static charge
friction
induction
direct contact
two basic types of current electricity
direct current
alternating current
Voltage of a series battery cell
total of all individual cells
Voltage of an alternating battery cell
voltage of an individual cell
Resistance of a series battery cell
Increases with number of cells
Resistance of an alternating battery cell
less than that of any single cell in the circuit
A __________ is a semiconductor that amplifies alternating current
transistor
The three laws of magnetism
a nonmagnetic ferromagnetic metal is attracted by either pole of a magnet
like magnetic poles repel one another
unlike magnetic poles attract one another
Three ways in which magnetism can be affected by outside influences
heat
interaction with another magnetic field
mechanical action
Magnetic field of a solenoid is directly proportional to
turns of wire
current passing through
Magnetic field of a solenoid is inversely proportional to
the length of the solenoid
Three types of nuclear reactions
fission
fusion
radioactive decay
Three most common radioactive emissions
