Afish is looking at a 1.0 m high plant at the edge of a pond. will the plant appear to the fish shorter or taller than its actual height? draw a ray diagram to explain your answer.

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?
