Almost all telescopes have a circular mirror. The area of a circle is proportional to

where

is the radius of the circle, the constant of proportionality being


Therefore the area of 150 meter telescope would be

times bigger than the area of the smaller (10 meter) telescope.
Answer:
a = 120 m/s²
Explanation:
We apply Newton's second law in the x direction:
∑Fₓ = m*a Formula (1)
Known data
Where:
∑Fₓ: Algebraic sum of forces in the x direction
F: Force in Newtons (N)
m: mass (kg)
a: acceleration of the block (m/s²)
F = 1200N
m = 10 kg
Problem development
We replace the known data in formula (1)
1200 = 10*a
a = 1200/10
a = 120 m/s²
