Density because any object that is more dense than water (density of 1. I forget the units) sinks, and any object less dense than water floats.
<span>"New information changed the understanding of the atom’s structure"
Whenever a scientific observation is made, it has to be verified and its interpretation over time may change due to understanding of the specific phenomenon. Scientists do not alter the observation in any way; instead, explanations are presented to fit the observations as best as possible.</span>
Answer:
2.1ppm
Explanation:
Nuclear magnetic resonance spectroscopy,NMR is use to measure local magnetic field around atomic nuclei. Nuclear Magnetic Resonance Spectroscopy,NMR is used to identify organic compounds. It gives details about organic compound structures. Also, Nuclear, Magnetic Resonance Spectroscopy, NMR is used by biochemists to discover the structure of proteins and other complex structures.
In order to calculate parts per million, ppm, we use the formula below.
Ppm= frequency (in hertz)/ MHZ
The signal at 2.1 ppm in a 1H NMR spectrum obtained using a 60-MHz spectrometer will still be the signal When the same sample is placed in a 300-MHz spectrometer, only the RESOLUTION will change.
Average velocity is displacement divided by time elapsed; Δv/Δt
You will need to use the information in the table you are given. Subtract: (final velocity - initial velocity) and divide by (final time - initial time).
Well one situation i can think of is a tire rolling on a car
(ill try to find more)
