All observers measure the same speed of light,
no matter how any observer is moving.

The question is kind of awkward, though. It seems to say that
people were having a hard time accepting this postulate of relativity,
until Michelson and Morley came along and did their experiment, and
their results gave Relativity a boost.

Actually, Michelson and Morley did their famous experiment in 1887.
At the time, Einstein was only 8 years old, and Relativity was not even
a twinkle in his eye yet.

If mass is measured in kg and acceleration is measured in m/s^2, what units would force be measured in? This unit is also know a

Vlada [557]

Mass=kg
Acceleration=m/s^2

Using Newtons second law

$\\ \sf\longmapsto Force=Mass\times Acceleration$

$\\ \sf\longmapsto Force=kgm/s^2$

$\\ \sf\longmapsto Force=Newton(N)$

Which hypothenical scenerio would you result in the moon not having dofferent phases? A.The moon takes twice as long as it does

maw [93]

<span>The hypothetical scenario that would result in the moon not having different phases would be t</span>he moon always stays in one position relative to the earth and sun. Why? If the moon didn't have an phases it would stay in one position. Phases mean change, and if you observe the moon every night, you'll see how it changes; it repeats, so thus it's a pattern.

So, your correct answer should be: <span>D.The moon always stays in one position relative to the earth and sun.</span>

Holden is trying to turn man the velocity of his car, he went 20 meters east, turned around and left 40 meters less, he turned t

Grace [21]

Answer:

3 m/s east

Explanation:

The velocity of the car is given by:

$v=\frac{d}{t}$

where

d is the displacement

t is the time taken

The displacement of the car does not depend on the path of the car, but just on it the difference between its final position and its starting position, so it is equal to 15 metres east. The time taken is 5 seconds, therefore the velocity is equal to

$v=\frac{15 m}{5 s}=3 m/s$

and the direction is east.
