In a mass spectrometer, a compound is first vaporized and converted into ions, which are then separated based on a difference in
Crazy boy [7]

The correct answer is  their difference in the charge to  mass ratio  a mass spectrometer, a compound is first vaporized and converted into ions .

Mass spectrometry is a technique for determining the mass-to-charge ratio (m/z) of one or more molecules in a sample. These measurements are frequently used to calculate the precise molecular weight of the sample components.

The speed at which positively charged ions move through a vacuum chamber toward a negatively charged plate is measured by mass spectrometers. ToF, magnetic sector, and quadrupole mass spectrometers are all commonly used in SIMS instrumentation.The MS/MS has three major advantages: the ability to study numerous molecules regardless of whether they are from the same structural family or not; the ability to highlight the specific metabolites of a disease; and it is an automated technique that allows for large-scale analysis.

A mass M tied to a light string is moving in a vertical circle. The tension in the string at the top is TT and TB at the bottom
natita [175]

Answer:

Explanation:

Tension provides centripetal force in the circular motion . In circular motion work done by force = torque x angle

torque is zero as , centripetal force passes through axis of rotation that is center.

So work done by centripetal force  = 0

So work done by tension on M = 0

at which velocity would you expect an object to have the greatest amount of kinetic energy? a. 11-20 m/s b.0-10 m/s c. 21-30 m/s
UkoKoshka [18]

Answer:

31-40 m/s

Explanation:

The kinetic energy of an object is given by :

E=\dfrac{1}{2}mv^2

m is mass of the object

v is velocity

If mass of an object is constant, its kinetic energy depends only on velocity. It means if the velocity is more, it will have maximum kinetic energy. For the interval of 31-40 m/s, the kinetic energy of the object is maximum.
