Me with question 4 i’ve use the formula and still wrong answer

3770 m/s

Explanation:

V = (GM × 2π/T)^⅓

Given:

G = 6.67×10⁻¹¹ m³/kg/s²

M = 5.97×10²⁴ kg

T = 13.00 hr = 46,800 s

V = (6.67×10⁻¹¹ m³/kg/s² × 5.97×10²⁴ kg × 2π / 46,800 s)^⅓

V = 3770 m/s

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
