  • What determines the length of the base in a dimensional analysis problem?
    In dimensional analysis, the length of the base is determined by ensuring that the units on both sides of an equation are consistent and match each other.
  • By contrast, how does dimensional analysis differ from numerical calculations?
    Dimensional analysis differs from numerical calculations as it focuses on unit consistency and simplification without requiring actual numerical values.
  • Which row (a) in a table of equations is dimensionally consistent?
    A row in a table of equations is dimensionally consistent if the units on both sides of each equation match after simplification.
  • Which of these is mismatched in terms of unit consistency?
    A mismatched term in terms of unit consistency would be one where the units do not align or cancel out properly, leading to an incorrect equation.
  • While preparing to divide units in dimensional analysis, what should be considered?
    While preparing to divide units in dimensional analysis, ensure that units cancel appropriately to maintain dimensional consistency across the equation.
