Answer: Time and space depend on reference frames, but the speed of light does not.

Explanation: According to Einstein Space and Time are directly related as the way we sense them, in his words space and time is like a fabric in which we cannot affect one without affecting the other as we interact with it, time can be stretched and squeezed depending on your inertial frame of reference (constant speed and mass). However light can travel thru the fabric of space and time and it does not get affected by any reference keeping always the same speed.

Levart [38]

Answer:

A: For each 1 degree Celsius that temperature decreases, the speed of sound decreases by 0.6 m/s. So sound travels through dry, -20 °C air at a speed of 319 m/s

The Milky Way and Andromeda galaxies are members of the Local Group, a cluster of more than 50 galaxies spread across a spherica

fenix001 [56]

Answer:

2400 cm

Explanation:

The milky way has diameter of 100000 light years.

$100000\ ly=24\ cm\\\Rightarrow 1\ ly=\frac{24}{100000}\ cm$

The local group is the collection of galaxies which includes the milky way.

10 million light years is the diameter of the local group.

$10\times 10^6\ ly=10\times 10^6\times \frac{24}{100000}\ cm\\\Rightarrow 10\times 10^6\ ly=2400\ cm$

Hence, the diameter of the scale model of the local group would be 2400 cm

Which measurement is the most precise?? 27 m 27.7 m 27.791 m 27.79 m

Vera_Pavlovna [14]

Answer: 27.791 meters

Explanation: The precision of a measure depends on the number of significative decimals that it has, so the number that is most exact is the one with more numbers after the decimal point, in this case, is the third option: 27.791 m

This one is the most exact because you know that the lenght is:

27 meters, 7 centimetrs and 9.1 milimeters
