Janet wants to find the spring constant of a given spring, so she hangs the spring vertically and attaches a 0.63 kg mass to the spring's other end. if the spring stretches 2.8 cm from its equilibrium position, what is the spring constant?

Consider two regions of space containing a static electric field, region a and region b. in region a the equipotential lines are more closely spaced than those in region b. what can be said about the relative strength of the electric field in the two regions? a) the electric field in region a is stronger th
