2An irregularly shaped object is floating in water. Its weight is 735 N. The buoyancy force is 700 N. What is the volume of the object submerged in the water? (Refer to MT1 solutions, Part 2, problem 1a)
3Consider the aluminum cube dropped into a water/ice mixture described in MT1 solutions, Part 2, problem 2. If the final temperature is calculated to be 23.6°C, what can be inferred about the state of the mixture?
4A monatomic ideal gas undergoes an adiabatic compression. Which of the following statements are true about this process? (Refer to MT1 solutions, Part 2, problem 4)
5In the context of an electric dipole, what is the fundamental reason why electric field lines cannot cross? (Refer to Winter 2019 Midterm 2 Solutions, problem 5)
6Consider an electric dipole with charges +q and -q separated by a distance d. If this dipole is placed in an external electric field E, what is the torque $ au$ experienced by the dipole?
