What was the general feeling during the first period of environmental policy?

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

How is the gravitational force related to the distance between two objects?

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?
