The answer is TRUE.
answer:answer is second postulate (invariance of c)
explanation:postulate (principle of relativity) laws of physics take the same form in all inertial frames of reference. postulate (invariance of c) measured in any inertial frame of reference, light is always propagated in empty space with a definite velocity c that is independent of the state of motion of the emitting body. or the speed of light in free space has the same value c in all inertial frames of reference.
the two-postulate basis for special relativity is the one historically used by einstein, and it remains the starting point today.
here are the observation between a simulated and an actual volcano eruption:
1. the chemical that causes the eruption of a simulated volcano eruption comes outside of the dummy volcano (through pouring down the vinegar). on the other hand, an actual volcano eruption comes from inside (magma).
2. the fake lava that has come out of the dummy volcano only looks hot but it’s not and the color is clear (color of the vinegar), while the real lava is super hot and it has a fiery color (red orange)
3. the fake lava wets the surface of the dummy volcano because of the vinegar, while the real lava creates a deformation on the surface of the real volcano depending on how runny and fast the magma moves inside it.if you want to know more about volcanoes click this link:
