Triangular pulses of light a laser emits triangularupulses of light (? = 905 nm). each pulse has a duration ? -5 ns and contains 1011 photons. the repetition frequency is 10 mhz. question 1: how much radiant energy (in j) does each pulse contain? answer question 2: what is the peak power (in w) of each pulse?question 3: what is the average power (in w) of each pulse? answer question 4: what is the average output power (in w) of the laser?

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
