If the tension in the string is 75n, the angle is 64, and the period is 2s, calculate: a) the mass of the pendulum b) the radius of the horizontal circle

Objects a and b are visible in the night sky. six months later they are still visible, but object b shows less parallax than object a. which object is closer? a. a b. b c. you would need to wait another six months in order to figure this out. d. you would need to know the objects' angular diameters in order to figure this out.
