  6. What is the equation for pressure due to a height of liquid or gas?
    • p = h ρ g
    • ρ = density of liquid (or gas)
  7. What is the equation for work done
    W = F d

    where d = distance moved in the direction of the force
  8. What is the equation for potential difference in terms of current(I), resistance(R)
    V = I R

    • V = potential difference
    • I = current
    • R = resistance
