FINAL TESU PHYSICS 116 | QUESTIONS AND ANSWERS | VERIFIED
AND WELL DETAILED ANSWERS | LATEST EXAM
why cant we travel at 99.99% the speed of light - CORRECT ANSWER - not
enough propulsive energy and shielding against radiation.
hypothetical particles that could move both faster than light and backward in
time are called - CORRECT ANSWER - tachyons
how may observers in universe see us from their point of view - CORRECT
ANSWER - they see us living in slow motion
what does the concept of time apply to - CORRECT ANSWER - events and
entities within the universe, not the universe as a whole
where does spacetime exist - CORRECT ANSWER - WITHIN the universe
as the speed of an object approaches the speed of light, its momentum? -
CORRECT ANSWER - approaches infinity
photons of light are - CORRECT ANSWER - massless
a piece of matter, even at rest and not interacting with anything else, has an
"energy of being" this is called - CORRECT ANSWER - rest energy
E=mc^2 what does C^2 mean - CORRECT ANSWER - conversion factor
between energy units and mass units. it converts the measurement of mass to the
measurement of equivalent energy
, A change in energy of any object at rest is accompanied by a change in -
CORRECT ANSWER - its mass
The filament of a lightbulb energized with electricity has - CORRECT
ANSWER - more mass than when turned off.
E=MC^2 is the ratio of - CORRECT ANSWER - rest energy to mass
a speck of matter with a mass of only 1 mg has a rest energy of - CORRECT
ANSWER - 90 billion J
Energy and mass are - CORRECT ANSWER - the same thing. if you want to
know how much energy is in a system measure its mass
The ratio v^2 / c^2 is very small and for everyday speeds may be taken -
CORRECT ANSWER - to zero
if the acceleration of the spaceship were equal to G the occupants could well be
convinced that the ship - CORRECT ANSWER - was not accelerating but was
at rest on the surface of earth
state the principle of equivalence - CORRECT ANSWER - observations made
in an accelerated reference frame are indistinguishable from observations made
in a Newtonian gravitational field
you throw a ball in a (straight-line path) accelerating ship what does the
observer see and what does the man in the spaceship see - CORRECT
ANSWER - observer= straight line path
man in ship= path is curved.
key word accelerating ship
