Lasers can be constructed that produce an extremely high intensity electromagnetic wave for a brief time—called pulsed lasers. they are used to ignite nuclear fusion, for example. such a laser may produce an electromagnetic wave with a maximum electric field strength of 1.52\times 10^{11}~\text{v/m}1.52×10 11 v/m for a time of 1.00 ns. what energy does it deliver on a 1.00~\mathrm{mm^2}1.00 mm 2 area?

30 points - when can a theory be modified if a new type of technology allows for new observations that raise new questions? a. immediately, while the questions about the theory are being asked b. after new hypotheses related to the theory are tested in experiments c. only after the new observations disprove all parts of the theory d. while scientists begin to think about how the theory could improve

What is a carrier wave and how does it affect what you hear on the radio

Aperson walks first at a constant speed of 4.89 m/s along a straight line from point a to point b and then back along the line from b to a at a constant speed of 2.95 m/s. what is the average speed over the entire trip?
