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.

If you toss a ball straight upward at 40 m/s with no air resistance, what will be its speed 2 seconds later? Explain your answer
Kamila [148]

Answer:

Final speed of the ball, v = 20 m/s.

Explanation:

It is given that,

Initial speed of the ball, u = 40 m/s

Time. t = 2 s

We need to find the speed of the ball after 2 seconds. Let it is denoted by v. It can be calculated using first equation of motion as :

v=u+a\times t

Here, a = -g, as the ball is ball is moving under the action of gravity.

v=u-g\times t

v=40-10\times 2

v = 20 m/s

So, the speed of the ball after 2 seconds is 20 m/s. Hence, this is the required solution.

Suppose a child drives a bumper car head on into the side rail which exerts a force of 4000 N on the car for 0.200 s. What impul
Ghella [55]

Por the impulse, use the formula:

I = F * t

Now, we know:

4000 N = 4000 kg*m/s²

Replacing we have:

I = 4000 kg*m/s² * 0,200 s

Resolving:

I = 800 kg.m/s²

The impulse is <u>800 kg.m/s²</u>
