PET is combined with some current imaging techniques to produce both functional and anatomical information. One of these combined approaches involves an increase in the ionizing radiation experienced by the patient. Which hybrid technique is this? PET/CT PET/MRI PET/Ultrasound

What object a collides with object b and bounces back its final momentum is?

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
