1. describe the formation of the four types of fronts and the weather associated with each 2. how does the burning fossil fuels influence global temperature. how might the change in temperature affect other parts of earth, such as the hydrosphere and biosphere

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?
