This is for something I'm writing, not a real case of ear infection. I don't need any other advice or info about seeing a doctor, taking alternative medicines, etc. Just, specific antibiotics, and specific costs. (And I know costs vary. It doesn't matter. I'm still asking for specific prices- I don't care if they're high end, low end, or middle.)

During a moon landing, one of the experiments performed was the measurement of the intensity of solar wind. As a collector, an aluminum strip of about 3,000.000 square centimeters was used. It was found that in 100.00 minutes, a mass of 3.00 x 10^-10g of hydrogen was collected. What is the intensity of the solar wind (number of atoms per sq. centimeter per second?).

I heard that the moon is slowly but steadily pulling earth towards it, and im arguing with my friend, who thinks the earth is being pulled into outer space slowly. We both know that it is not going to be immediate, I know. But Im looking online for the answer, and I find mixed results, not finding a definate answer. Which is it?
