When we dip our finger in the water, the water exerts upward thrust on the finger (Archimedes’s principle). Due to Newton’s third law of motion, the finger will exert an equal and opposite force on the water in downward direction resulting in increase of the weight of water. Thus the reading of the spring balance will increase.

7. In the particle-in-a-half-baked-well problem, you see that the wavefunction decayed exponentially into the barrier when E < V as shown on the left. Now the question is - what do you think happens if the right barrier was "thin", such that the wavefunction doesn't decay to 0 before the end of the barrier as shown here? Please draw and explain your result. (5 pts)

Texts: 2. Assume that you drop a 3D ellipsoidal object carefully in honey as you can see in the right figure. (The radius of the long axis is 6 mm, and the radius of the other two short axes is 2 mm. The mass of the object is 0.5 g.) Assume g = 9.8 m/s^2.
  1. a) By assuming that the Reynolds number is very small, and that the inertial term (ma) is negligible compared to the viscous drag force (i.e. F = F in each direction), calculate the velocity of the object (as a vector like ai + bj).
  2. (b) Calculate the Reynolds number using the velocity obtained in (a). Was the assumption of a low Reynolds number in (a) valid?
