When water freezes, it expands about 9.80%. what would be the pressure increase inside your automobile's engine block if the water in it froze? (the bulk modulus of ice is 2.00×10^9 n/m^2.)

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?
