Tracking data for the positions of two earth satellites are provided below. calculate the position vectors from the tracking station to the satellites in the azimuth-elevation topo-centric coordinate system for each set of data. (a) ρ.-1.375 km, az.-102.4°. el,-42.1° (b) p2 = 2,711 km, az, = 273.1°. el,-53.4。

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
