Using s=1/2 a t ^2
25 = 1/2 x 0.5 x t^2
t = square root (25/0.25)
t = 10 seconds
This year Venus was slim crescent in March when the Earth-Venus was about
(the minimum distance)
To find its angular diameter we apply the trigonometry
where D=21000 km is the planet diameter and L is the distance to the planet. For small angles we consider
Thus the angular diameter of venus when it was slim crescent was
In degrees this is
We know that 3600 seconds correspond to 1 degree. Therefore
Hence
Therefore the angular diameter of Venus when it was slim crescent was 60''.
False because the allocation rule of "first come-first served" promotes productive cooperation.
