Answer:
Astronomers
Explanation:
Astronomy
Field of study
DescriptionAstronomy is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry to try and explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets.

Apply Newton's second law of motion to the car:
F = ma
F is the driving force moving the car, m is the car's mass, and a is the car's acceleration.
Assuming we apply the same F to another more massive car, it would move with a smaller acceleration.
Answer:
D. because the light is reflected back into the fiber along its sides
Explanation:
The fiber is constructed in a way that the light is bent/reflected/refracted toward the center core of glass. So, from the center core, there is a layer above it that has a different propagation than the core, and above that the same thing. To give you a real world visual example, if you look down in a pool of water, then stick a straight stick into it, you see that the straight stick appears to bend. That is what is happening to the light as it travels through a different medium (air to water). This same effect is incorporated in the fiber optic cable construction.
Answer:
orbital period increased by a factor of 2.83 unit
Explanation:
Given.
planet’s orbital period, T, and the planets mean distance from the sun, A, in astronomical units, AU
T²= A³
If A is increased by a factor of 2 , .
Then T will be increase with the factor of √2³ = 2.83
