Galactic Rotation Speed. We are located about 27,000 light-years from the galactic center and we orbit the center about once eve

Alexxandr [17]

Answer:

speed = 796142.197 km/hr

Step-by-step explanation:

solution

we consider here orbit around galactic center is circular so

circumference formula will be here

circumference C = 2πr ........1

here we know r = 27000

circumference C = 2 π × 27000

C = 169560 light year

we travel 169560 light year in 230000000 years

so distance will be

distance = $\frac{169560}{230000000}$

distance = 0.00073721 light year/year

and we know 1 year = 8760 hours

so 1 light year = 9.46027 × $10^{12}$ km

sped of moving is

speed = 0.00073721 × 9.46027 × $\frac{10^{12}}{8760}$ km/hr

speed = 796142.197 km/hr

STALIN [3.7K]

Answer:

4. 30 inches

5. 76.2 cm

6. 1024 sqaure inches

Step-by-step explanation:

4. √900 = 30 (area of a square = s²)

5. 30*2.54 = 76.2 cm

6. Each side is 2 inches longer ⇒ 30+2 = 32 inches (each side length)

area of a square = s²

32² = 1024 square inches
