Wavelengths of light from a distant galaxy are found to be 0.58% longer than the corresponding wavelengths measured in a terrestrial laboratory.

A) Is the galaxy approaching or receding from the earth?

B) At what speed?

The solar panels used by mark function because of the photoelectric effect. light shines on the cells causing electrons to be ejected from the metal, which produces an electric current. at night on mars, no light will fall on the solar cells and no electric current will be generated. according to your notes, what type of light is typically needed to cause the photoelectric effect? a)visible b)ultraviolet c)infrared

Which component is used to measure the current in a circuit? oa. switch ob. resistor oc. ammeter the answer is c. for y’all plato people

Given the data calculated in parts a, b, c, and d, determine the initial rate for a reaction that starts with 0.85 m of reagent a and 0.70 m of reagents b and c?
