What is the instrument used to measure length? Length, or the distance between two lengths: Tools used to measure length include a ruler, a Vernier caliper, and a micrometer screw gauge. Vernier calipers and micrometer screw gauges are more precise and can be used to measure the diameter of objects like pipe and wire. What […]
Do elements have life?
Do elements have life? 1. Note that most living matter consists primarily of the so-called bulk elements: oxygen, carbon, hydrogen, nitrogen, and sulfur—the building blocks of the compounds that constitute our organs and muscles….Classification of the Essential Elements. Bulk Elements (kg) nitrogen 1.8 Macrominerals (g) chlorine 115 Are Chemical living things? All living things share […]
Can water flush out alcohol?
Can water flush out alcohol? Water can help reduce your BAC, though it will still take one hour to metabolize 20 mg/dL of alcohol. What happens to your body when you drink everyday? Drinking too much puts you at risk for some cancers, such as cancer of the mouth, esophagus, throat, liver and breast. It […]
Do phonons actually exist?
Do phonons actually exist? Phonon is considered a quasi-particle, beacuse it can exist only in solids as a consequence of vibrational motions: they cannot propagate in vacuum. > as a consequence of vibrational motions: they cannot propagate in vacuum. Do phonons have mass? A phonon — a particle-like unit of vibration that can describe sound […]
What is experiment in data collection?
What is experiment in data collection? Experiment. An experiment is a controlled study in which the researcher attempts to understand cause-and-effect relationships. The study is “controlled” in the sense that the researcher controls (1) how subjects are assigned to groups and (2) which treatments each group receives. What is the purpose of data in an […]
Why base is kept very thin in transistor?
Why base is kept very thin in transistor? The base region in a transistor is made very thin so that there is a better conduction of majority carriers from emitter to collector through base. The base region in a transistor is doped lightly so that the number density of majority carriers (electrons in p-n and […]
What are the six most common NDT methods?
What are the six most common NDT methods? The six most frequently used NDT methods are eddy-current, magnetic-particle, liquid penetrant, radiographic, ultrasonic, and visual testing. Is NDT dangerous? Certain nondestructive testing methods used by the military, such as ultrasonic or eddy current testing, are almost entirely benign and do not pose a hazard to testing […]
What is the electrostatic attraction?
What is the electrostatic attraction? Electrostatic attraction refers to the electrostatic force of long-range interaction occurring between the attractive electrostatic adsorption in aqueous solution with differently charged particles or uncharged particles. What increases electrostatic attraction? The net attractive electrostatic attraction is increased as the nuclear charge increases. Electrons are being added to successive energy levels […]
