A physics professor sitting on a stationary reference frame gives an exam to the students who are on a spaceship traveling at a speed vrelative to stationary frame. The moment the ship passes the professor, she signals the start of the exam. If she wishes her students to have time T0(spaceship time) to complete the exam, how much time should the professor wait (in the stationary frame) before sending a light signal telling them to stop? Draw a spacetime diagram and express the answer time in terms of T0and vand c.

One splits the atoms and molecules  the other combines them

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

How are period and frequency related to each other? dperiod is the reciprocal of frequency.
