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.

Explanation:
Given data
mass m=1000 kg
building height=10 m
To
Find work
Solution
As we know that:
So option (C) is correct one
Answer:
density of water is much greater than density of air
Explanation:
when body is in fluid it carries weight which is always equal to upthrust
upthrust is given as
upthrust= density of fluid ×strength of gravitational field g × volume of body in fluid
as volume of ship and aeroplane is same and strength of gravitational field or acceleration due to gravity is same hence upthrust depens upon density of fluid .
density of air is about 1.2 kg/m^3 and density of water is 1000kg/m^3 hence ship carries more load
Answer:
Distance, S = 130m
Explanation:
Given the following data;
Initial velocity = 2m/s
Final velocity = 28m/s
Acceleration = 3m/s²
To find the distance, we would use the third equation of motion.
V² = U² + 2aS
Substituting into the equation, we have;
28² = 2² + 2*3*S
784 = 4 + 6S
6S = 784 - 4
6S = 780
S = 780/6
Distance, S = 130m
Light waves are different from mechanical waves, however, because they can travel through a vacuum. Light waves are just one type of electromagnetic wave. ... A polarized wave vibrates in a single plane in space. Since sound waves vibrate along their direction of propagation, they cannot be polarized.
