Question

On Earth, the Sun appears to move 15˝/hr across the sky.

Answer 1

Answer:

speed of apparent on moon = 0.50847° per Hour

speed of apparent movement on Jupiter= 36.36° per Hour

Explanation:

given data

Sun appears to move =  15˝/hr

to find out

How many degrees per hour would the Sun appear to move if we at equator of the Moon and How many degrees per hour would the Sun appear to move if we at the equator on Jupiter

solution

we know that sun is stable it not move but earth is revolving around that sun but it appear sun rise

so movement of sun in sky 360° every day

and time taken = 24 hours

so as we have given

speed of the apparent movement=$\frac{360}{24}$°/Hour = 15 °/Hour

so

we have given Time taken by the sun to Moon's sky = 29.5 days  = 29.5 × 24 = 708 hours

so

speed of apparent on moon = $\frac{360}{708}$

speed of apparent on moon = 0.50847° per Hour

and

we know Time taken by the sun to Jupiter = 9.9 hr

so

speed of apparent movement on Jupiter= $\frac{360}{9.9}$

speed of apparent movement on Jupiter= 36.36° per Hour
