It's because negatively charged ions would not be attracted to the negative plate so it's not accelerated and thus it would not reach the detector.
Everything. About the only thing they have in common is "you learn about them in analytical chemistry class."Except "Nuclear Mass Resonance Spectroscopy", which doesn't exist and I assume is an error that should have read "Nuclear Magnetic Resonance Spectroscopy".X-Ray spectroscopy gives you the conformation in a fairly direct (okay, it's actually not all that direct) manner.NMR spectroscopy mainly gives you chemical structure information; you can finesse it a bit (NOESY and related techniques) to give some conformational information.Mass spectroscopy is pretty much chemical structure only (and, again, it's not all that direct, it just tells you what fragments the molecule breaks apart into; figuring out how they fit together is your problem).
No, it only can measure weight.
Mass spectroscopy can be used for a series of applications, ranging from the determination of chemical elements and chemical compounds in all kinds of samples to the investigation of reactions and interactions of DNA with other substances. As in mass spectroscopy you detect chemical substances based on the ratio between their masses and the charges (only ions can be detected), a wide range of information can be obtained usually with only very low amounts of the substance that you want to investigate.
No, liters measure volume and volume only.
A Newton. Not a kilogram, which is a measure of mass, not weight. And cetainly not pounds or stones which are not only measures of mass but are used by few countries.
A spring device can only measure an object's weight. In order to find its mass, you then have to either compare its weight with the weight of a known mass, or else use the value of gravitational acceleration to calculate the mass from the weight.
Technically, it's not. It's only attractive between two positive masses or two negative masses. One positive mass and one negative mass would repel each other. It's just that we've never encountered a piece of negative mass yet.
There is only one and that is a kilogram.
No a balance can not measure volume however it does measure mass. You can find the volume by using the balance to find the mass of what ever you want then if you know the density of the thing then you simply divide the mass by the density.
If you mean, convert µg to cm², that conversion doesn't make sense. You can only convert units that measure the same kind of thing, for example, one unit of mass to another unit of mass.
Vaccination is only a preventative measure, it will not cure influenza.
A gram is often thought to be a measure of weight but it is really measure of mass. A gram serves as a unit for weight only when in the gravity field of the Earth.
