Suppose a particle of mass m is confined to a one-dimensional box of length l. we can model this as an infinite square well in which the particle's potential energy inside the box is zero and the potential energy outside is infinite. for a particle in its first excited state, what is the probability of finding the particle within the center 20% of the box?

The federal reserve controls certain interest rates in the united states. investors often try to speculate as to whether the federal reserve will raise or lower rates and by how much. suppose a company conducts extensive interviews with financial analysts, and as a result, predicts that "thefed" will increase rates by an average of 0.25 percentage points every six months for the forseeable future. which type of equation could be used to model the predicted interest rates over the next several years, assuming no other significant changes? a) a linear equation b) a quadratic equation c) a polynomial equation d) an exponential equation
