Bushong-Chapter 02 - Basic Physics
Primer
Which of the following is the SI unit for power? - answerJoule/second
(The SI unit of power is the joule/second (J/s), which is a watt (W).)
Thermal radiation is the transfer of heat by the emission of ___________________. -
answerinfrared radiation
(Thermal radiation is the transfer of heat by the emission of infrared radiation.)
Express 6849 in exponential form. - answer6.849 × 10^3
(6849 = 6.84 × 10^3)
X-rays have a velocity of 300,000,000 m/s. Express this in exponential form. -
answer3.0 × 10^8 m/s
300,000,000 m/s = 3 × 10^8 m/s
Which units are considered base quantities? - answerMass, length, and time
(The base quantities are length, mass, and time, and they are the building blocks of all
other quantities.)
Which of the following are special quantities used in radiologic science? -
answerExposure, dose, effective dose
(Exposure, dose, and effective dose are special quantities used in radiologic science.)
Which of the following is Newton's first law of motion? - answerA body at rest will remain
at rest and a body in motion will continue in motion with constant velocity unless acted
on by an external force.
(Newton's first law of motion states that a body at rest will remain at rest and a body in
motion will continue in motion with constant velocity unless acted on by an external
force.)
Which of the following is Newton's third law of motion? - answer(For every action, there
is an equal and opposite reaction.)
Newton's third law of motion states, for every action, there is an equal and opposite
reaction.
Which of the following states the law of conservation of energy? - answerEnergy may
be transformed from one form to another, but it cannot be created or destroyed.
(The law of conservation of energy states that energy may be transformed from one
form to another, but it cannot be created or destroyed.)
