What are emission spectrums used for? A spectroscope can be used to determine which frequencies have been emitted by a substance. The emission spectrum is a combination of the atomic spectra of the various kinds of atoms making up the substance and can be analyzed to determine the substance’s chemical or atomic composition. What do […]
What is the relation between current and resistance?
What is the relation between current and resistance? The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. What is a specific resistance? […]
What is LS coupling explain with example?
What is LS coupling explain with example? The energy levels which are characterised by certain values of L and S are called terms and the coupling of angular momenta of individual electrons to a resulting orbital angular momentum and spin is referred to as LS-coupling or Russell-Saunders coupling. Which is the selection role for LS […]
What are the six sensory receptors?
What are the six sensory receptors? Sensory receptors exist in all layers of the skin. There are six different types of mechanoreceptors detecting innocuous stimuli in the skin: those around hair follicles, Pacinian corpuscles, Meissner corpuscles, Merkel complexes, Ruffini corpuscles, and C-fiber LTM (low threshold mechanoreceptors). What do all receptors have in common? What do […]

What is the heat of solution quizlet?
What is the heat of solution quizlet? heat of solution. the amount of heat absorbed or released when a solute dissolves in a specific amount of solvent. What is heat of solution measured in? The enthalpy change is observed when the solute is dissolved in the solvent. When solid or gas is dissolved in the […]
How do electromagnetic fields affect the human body?
How do electromagnetic fields affect the human body? Low-frequency magnetic fields induce circulating currents within the human body. The strength of these currents depends on the intensity of the outside magnetic field. If sufficiently large, these currents could cause stimulation of nerves and muscles or affect other biological processes. How does frequency affect the human […]

Blanching (lighter skin around the IV site) Pain or tenderness around the site. IV not working. Cool skin temperature around the IV site or of the scalp, hand, arm, leg or […]
How do I know if my steering rack is part of routine maintenance?
How do I know if my steering rack is part of routine maintenance? Checking the steering box A typical steering-box layout. Check the gasket and seals for leaks, and the moving parts for wear. Measure steering-wheel travel by making a chalk mark on the rim and using your finger as a reference point. Try to […]
