Couple of questions, problem solving I've been stuck on for days.

    3questions on dimensional analysis, and problem solving various topics

    2. The attempt at a solution
    For questions 7 i had no clue what to do, for 9, i did the first part and got that the dependence was Drag force was proportional to ρAv2
    and 10 I wasn't sure how to approach this either

    Help would be much appreciated :) or hints for that matter
