What is the final velocity of a rocket that is traveling at 205 m/s and accelerates at
-Dominant- [34]

Answer:

70,100 m/s

Explanation:

Given:

v₀ = 205 m/s

a = 8.03 m/s²

Δx = 1750 m

Find: v

v² = v₀² + 2aΔx

v² = (205 m/s)² + 2 (8.03 m/s²) (1750 m)

v = 70,130 m/s

Rounding to three significant figures, the final velocity is 70,100 m/s.

What are the two principle advantages of telescopes over eyes?
Stells [14]

Answer:

i) Telescopes can be used to view far distant objects but the human eye can't view far distant objects.

ii) Telescopes uses two convex lenses producing a magnified image while the human eye only possesses one convex lens (image seen are smaller than that viewed under telescopes)

Explanation:

The telescopes can be used to view far distant objects due to their presence of two convex lenses. The two convex lenses are the objective lens (lens closer to object) and the eye piece lens (lens closer to eye). The object to be viewed forms an intermediate image first before the final image is seen using the eye piece lens.

The human eye only possess one convex lens and as such cannot view far ranged objects.
