The following are properties of three different sinusoidal, traveling electromagnetic plane waves. rank the waves in order from highest to lowest intensity. a. wavelength = 550 nm, magnetic field amplitude = 9 x 10-7 t b. wavelength = 1.20 µm, electric field amplitude = 600 v/m c. wavelength = 2.00 cm, average energy density of wave = 1 x 10-7 j/m3 group of answer choices

Note: the following questions are unrelated to the balmer series or the martian. refer to your course notes. a sun-sized star will spend most of its lifetime as a: white dwarf b. red giant c. protostar d. main-sequence star

If anyone who can me with this hw? i would really appreciate it

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
