E=mc^2 what does C^2 mean - <<<<ANSWERS>>>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 -
<<<<ANSWERS>>>its mass
The filament of a lightbulb energized with electricity has -
<<<<ANSWERS>>>more mass than when turned off.
E=MC^2 is the ratio of - <<<<ANSWERS>>>rest energy to mass
a speck of matter with a mass of only 1 mg has a rest energy of -
<<<<ANSWERS>>>90 billion J
Energy and mass are - <<<<ANSWERS>>>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 -
<<<<ANSWERS>>>to zero
why cant we travel at 99.99% the speed of light - <<<<ANSWERS>>>not
enough propulsive energy and shielding against radiation.
hypothetical particles that could move both faster than light and backward
in time are called - <<<<ANSWERS>>>tachyons
how may observers in universe see us from their point of view -
<<<<ANSWERS>>>they see us living in slow motion
what does the concept of time apply to - <<<<ANSWERS>>>events and
entities within the universe, not the universe as a whole
