ARMRIT Exam Questions With 100% Correct Answers | Updated & Verified 2024/2025 (GRADED)Studies have concluded that static magnetic fields up to what tesla produce no substantial harmful biological effects. - C)2.0 Tissues that have low (short) relaxation times have: - Higher relaxation rates Nuclei in their natural enviroment ( in the absence of a significant magnetic field) are aligned... - Randomly Following the injection of a gadolinium enhancement agent, the pulse sequence most commonly...

Scalar correct answers quantities with only magnitude such as speed, distance, time and mass. Vector correct answers quantities with a magnitude and direction e.g. acceleration, force momentum and weight. A vector quantity can be represented as an arrow, the size representing the magnitude and the direction, the direction. Non-contact force correct answers the objects are physically separate e.g. magnetism/gravity/electrostatic. 3 non-contact forces correct answers magnetism gravity...
