A glass ball of radius 2 cm is placed in a vertical cylindrical vessel of radius 20 cm filled with water and rotating at an angular velocity Ω about the axis of symmetry of the cylinder. After equilibration, the vessel, the water in the vessel, and the ball rotate at the same angular velocity 10 rad/s, the ball being on the bottom at the vertical wall of the rotating vessel. Find the force with which the ball acts on the vessel. Glass density is 2.5 g/cm^3, water density is 1 g/cm^3. Freefall acceleration is 10 m/s^2.

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop
