The apparent (bolometric) magnitude of the sun is mo-26.83. using this, the solar lumi nosity and the astronomical unit (a) derive an expression for apparent magnitude m(f) where f is the flux from an observed star. make sure to be clear about your units. the apparent magnitude of a star is m +5. (b) what is the fux from this star in watts/m2? (c) what is the ratio of fluxes f/ f. un? (d) how does this compare to the fux from a 60 watt light bulb at 2 meters? (e) how much power is collected from this star by your eye assuming a pupil diameter of 0.7 cm?

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

i don't understand. explain it clearly
