Relative to a stationary observer, a moving clock

always runs slower than normal.

One postulate of the special theory of relativity was that the laws of physics are the same in reference frames that

move at constant velocity with respect to an inertial frame.

The theory of special relativity

does not agree with Newtonian mechanics.

The Michelson-Morley experiment was designed to measure

the velocity of the Earth relative to the ether.

Michelson and Morley concluded from the results of their experiment that

Expt was a failure since no detectable shift in the interference pattern.

You can build an interferometer yourself if you use the following components:

light s, detector screen, partly silvered m, 2 flat mirrors, a glass plate.

U r in a spaceshp dt has no wndows, or ader mins 2 c wht is outsde. U wnt 2 know f d shp s stopped or moving @ constnt v

You should give up because you have taken on an impossible task.

The Lorentz factor or gamma factor is defined as Ɣ = 1 / √(1 - (v/c)2), therefore Ɣ

can be any number greater than or equal to one.

If you were to measure your pulse rate while in a spaceship moving away from the Sun at speed close to c, you would find

it is the same as it was here on Earth.

1
Relative to a stationary observer, a moving clock
always runs faster than normal.
can do any of the above.
keeps its normal time.
always runs slower than normal.
2
One postulate of the special theory of relativity was that the laws of physics are the same in reference frames that
move at constant velocity with respect to an inertial frame.
oscillate.
are stationary, but not in moving frames.
accelerate.
3
The theory of special relativity
does not agree with Newtonian mechanics.
is based on a complex mathematical analysis.
does not agree with electromagnetic theory.
has not been verified by experiment.
4
Relative to a stationary observer, a moving object
appears longer than normal.
keeps its same length time.
It depends on the relative velocity between the observer and theobject.
appears shorter than normal.
5
The Michelson-Morley experiment was designed to measure
the relativistic energy of the electron.
the velocity of the Earth relative to the ether.
the acceleration of gravity on the Earth's surface.
the relativistic mass of the electron.
6
Michelson and Morley concluded from the results of their experiment that
Expt was successful in detecting a shift in the interference pattern.
Expt was a failure since they detected a shift in the interference pattern.
Expt was a failure since no detectable shift in the interference pattern.
Expt was successful in not detecting a shift in the interference pattern.

You can build an interferometer yourself if you use the following components:
light s, detector screen, partly silvered m, 2 flat mirrors, a glass plate.
light, detector screen, partly silvered mirror, f mirror, glass plate.
light source, detector screen, 2 partially silvered mirrors, a glass plate.
light s, detector screen, 2 partly silvered m, flat mirror, a glass plate.

U r in a spaceshp dt has no wndows, or ader mins 2 c wht is outsde. U wnt 2 know f d shp s stopped or moving @ constnt v
You should give up because you have taken on an impossible task.
U cn determine if d ship is moving by determining the apparent v of light.
Either of the first two options.
Check if ur precision time piece. If it's running slow, the ship is moving.
9
The Lorentz factor or gamma factor is defined as Ɣ = 1 / √(1 - (v/c)²), therefore Ɣ
can be any number greater than or equal to one.
can be zero.
cannot equal one.
can be any number less than or equal to one.

If you were to measure your pulse rate while in a spaceship moving away from the Sun at speed close to c, you would find
it ismuch faster than normal.
it is much slower than normal.
it is the same as it was here on Earth.
