Science Test 3
Terms in this set (17)
Here you are taking this stupid test, oblivious to the imminent invasion of the blood-sucking slime creatures of Koozebane 7 who are at this moment flying along at 90% the speed of light toward the earth. According to relativity theory, what do the slime creatures notice about their pulse (assuming they have pulses), rate of aging, and other measures of time on the spaceship?
Everything seems quite normal.
In that same situation, what do the home-based creatures back at Slime Central on Koozebane observe about pulse rate, rate of aging, and other measures of time aboard the spaceship?
Everything seems slowed down
Zarnak, the science officer on the slime ship, is conducting experiments on the speed of light in space. He (she? it?) measures the speed of light from our sun, which you recall he is approaching at 90% the speed of light. What does Zarnak measure for the speed of light? (Zarn' knows that we use c as the normal speed of light.
Oh no! Zarnak and the crew are about to smash into a huge asteroid! How could they use relativity theory to go back in time one minute so they can make a course correction?
They can't! Not even with relativity can you go back in time.
What problem was Einstein trying to resolve with the Special Theory of Relativity? How can we
reconcile Newton's work with Maxwell's
The real meaning of E = mc2 is that
matter is a concentrated, tangible form of energy
One big difference between Newton's and Einstein's theories of gravitation is that
Einstein said gravitation should affect light, and Newton said it shouldn't.
Why do raindrops fall, according to Einstein?
The space around them 'squirts' them down.
Which of these is not a confirmation or test of the General Theory of Relativity?
The energy released by nuclear weapons and power plants.
Atoms are so hollow and empty that if you could take all the empty space out of your atoms, your body would be smaller than this º • (Yet of course you'd still weight the same!) What keeps the electrons from collapsing into the nucleus?
. Electrons are big waves that can't fit into the nucleus.
The source of all light in the universe is
What does it mean that atoms regenerate?
If disturbed, the electrons fall back into the same patterns.
The most fundamental statement of the uncertainty principle is that
there is no such thing as a definite electron, proton, neutron, or atom.
The two great pillars of modern physics are
general relativity and quantum theory
Which has more total energy: a bright light, a dim violet light, or all lights have the same amount of energy?
a bright red light.
Which has more energy, per photon: a bright light, dim violet light or all lights have the same amount of energy?
dim violet light
When does light act like a wave?
When traveling past us.
