A particle with a mass of 0.240 kg is attached to a horizontal spring with a force constant of 6 N/m. At the moment t = 0, the particle has its maximum speed of 12.5 m/s and is moving to the left. (Assume that the positive direction is to the right.) a. Determine the particle's equation of motion, specifying its position as a function of time.
b. Where in the motion is the potential energy three times the kinetic energy?
c. Find the minimum time interval required for the particle to move from x = 0 to x = 1.00 m. (Be sure to enter the minimum time and not the total time elapsed.)
d. Find the length of a simple pendulum with the same period.

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.

Why are nonmetals more likely to react with eachother by sharing electrons
