It's been a while since we did earthquakes, but I remember the terms epicenter and focus being used. Hope that helps.
Answer:
Given:
Radius of ball bearing (r) = 1.5 mm = 0.15 cm
Density of iron (ρ) = 7.85 g/cm³
Density of glycerine (σ) = 1.25 g/cm³
Terminal velocity (v) = 2.25 cm/s
Acceleration due to gravity (g) = 980.6 cm/s²
To Find:
Viscosity of glycerine ()
Explanation:
Substituting values of r, ρ, σ, v & g in the equation:
55 N moves it 8m is the correct answer, because if you multiply 55 time 8 you get 440 and that is the greatest number.
