What is a good rating for voltage drop test? With a good connection, there should be no drop, or at least very little (under 0.4 volts usually, and ideally under 0.1 volts). If the drop is more than a few tenths, then there’s too much resistance, the connection will have to be cleaned or repaired. […]
What is a isokinetic muscle contraction?
What is a isokinetic muscle contraction? An isokinetic muscle contraction occurs when the velocity of the muscle contraction remains constant while the length of the muscle changes. In an isokinetic concentric contraction, the muscle shortens while under load. In an isokinetic eccentric contraction, the muscle lengthens while under load. Is swimming isokinetic? The water provides […]
How many electrons does sodium ion have?
How many electrons does sodium ion have? 10 electrons Why is the sodium ion represented as Na+? Neutral sodium atom (Na) becomes sodium cation (Na+) by releasing an electron. positive charge on the sodium cation is balanced by the negative charge on the chloride, so the ionic compound is neutral. What is the difference between […]
What is caused by the collisions of gas particles with their container?
What is caused by the collisions of gas particles with their container? The collision of molecules with their container walls results in a momentum transfer (impulse) from molecules to the walls (Figure 10.7. 2). Figure 10.7. 2: Momentum transfer (impulse) from a molecule to the container wall as it bounces off the wall. How do […]
Where does salt we eat come from?
Where does salt we eat come from? Nutrition and healthy eating Sea salt is produced through evaporation of ocean water or water from saltwater lakes, usually with little processing. Depending on the water source, this leaves behind certain trace minerals and elements. What if we ran out of minerals? Minerals make up most of what […]
How do you calculate meters per second?
How do you calculate meters per second? The velocity in meters per second is equal to the distance in meters divided by time in seconds. How do I calculate my work hours? How to manually calculate employee hours Convert all times to 24 hour clock (military time): Convert 8:45 am to 08:45 hours. Next, Subtract […]
What is the primary function of a stretch reflex?
What is the primary function of a stretch reflex? The stretch reflex (myotatic reflex), or more accurately “muscle stretch reflex”, is a muscle contraction in response to stretching within the muscle. The reflex functions to maintain the muscle at a constant length. What do stretch receptors do? muscle systems …has important sensory structures called stretch […]
Which element has no electrical charge at all?
Which element has no electrical charge at all? Answer: Atoms of all elements – except for most atoms of hydrogen – have neutrons in their nucleus. Unlike protons and electrons, which are electrically charged, neutrons have no charge – they are electrically neutral. What is a subatomic particle with a positive charge? The nucleus contains […]
What is the electromagnetic spectrum simple definition?
What is the electromagnetic spectrum simple definition? Electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength. The electromagnetic spectrum comprises the span of all electromagnetic radiation and consists of many subranges, commonly referred to as portions, such as visible light or ultraviolet radiation. What is the electromagnetic spectrum and why is […]
Is neon shiny or dull?
Is neon shiny or dull? Element Luster Malleability Neon Colorless Not able to be stretched Silicon Dull, metallic Brittle, shatters when shaped Sulfur Dull Cannot be stretched Manganese Shiny Can be hammered into thin sheets Is helium bad for? The more pure helium you inhale, the longer your body is without crucial oxygen. Breathing in […]
