Rogue waves are a rare occurrence in which the amplitude of the wave can reach as high as 15 meters. Calculate the energy of rogue wave of this amplitude. Show your work.

The blackbody curve for a star name zeta is shown below. what is the peak wavelength for this star ?

Iwould appreciate if someone could me.

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
