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 5.0-Ω resistor and a 9.0-Ω resistor are connected in parallel. A 4.0-Ω resistor is then connected in series with this parallel
lbvjy [14]
The 4ohm resistor is not parallel to any devices, so the current through it is the same as the total current through the circuit.

Apply I = V/R
I = total current, V = battery voltage, R = total resistance

Calculate the total resistance R of the circuit first.

R will be the sum of the 4ohm resistor and the resistance of the 5&9ohm parallel resistors. To find the resistance of the pair, you apply the “sum of inverses” rule:

R = 1/(1/5 + 1/9) = 3.21ohm

Now add the 4ohm resistor:
R = 3.21 + 4 = 7.21ohm

Now let’s calculate I = V/R:
Given values:
V = 6.0V
R = 7.21ohm
Plug in and solve for I:
I = 6.0/7.21

I = 0.83A

Vera_Pavlovna [14]

-- Before Adrian left the airplane, his gravitational potential energy was

(mass) x (gravity) x (height) = (80kg) x (9.81m/s²) x (1,000m) = 784,800 joules


-- When he reached the ground, his kinetic energy was

(1/2) x (mass) x (speed)² = (40kg) x (5m/s)² = 1,000 joules


-- Between the airplane and the ground, the Adrian lost

(784,800 joules) - (1,000 joules) = 783,800 joules 

Where did all that energy go ?
Energy never just disappears.  If it's missing, it had to go somewhere.

The Adrian used  783,800 joules of energy to push air our of his way
so that he could continue his parachute jump, and reach the ground
in time to be home for dinner.
