A2.25 kg pumpkin oscillates from a vertically hanging light spring once every 0.85 s. a) find the equation giving the pumpkin's position ( upward) as a function of time , assuming it started by being compressed 17 cm from the equilibrium position (where = 0), and released.

Explain vector addition, triangle method and parallelogram method

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states

The amount of work done is determined by 2 factors. describe an example of work (using the scientific definition) list the 2 factors that determine the amount of work done.
