Answer fast for brainliest an optical telescope is an instrument that collects and reflects light from distant objects focuses light from very small objects stores heat from distant objects focuses light from distant objects

focuses light from distant objects

The last alternative is correct

Explanation:

An optical telescope is an instrument that collects  and focuses light from distant objects.

An optical telescope is an instrument designed to make distant object appear nearer.

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
