A wire is bent into a circular coil of radius r =4.4 cm with 21 turns clockwise, then continues and is bentinto a square coil (length 2r) with 33 turns counterclockwise. A current of10.8 mA is running through the coil, and a 0.350 T magnetic field is applied to the plane of the coil.(a) What is the magnitude of the magnetic dipole moment of thecoil?μcoil = 3Your answer is incorrect. A ·m2Find the magnetic moments of the circular part and the square partseparately and combine them together to get the total magneticmoment. Your response differs from the correct answer by orders ofmagnitude.(b) What is the magnitude of the torque acting on the coil?

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
