Yes, the data from mass spectrometry has helped modern scientists to make modifications to Dalton's model. 

Dalton's model consisted of a single atom and that basically the atom is the smallest object. At the time, no discovered what are inside of atoms. 

Atoms are made up of small particles, protons, neutrons and electrons. A mass spectrometer is an instrument that is able to see what is inside an atom. With this item, scientists have proved that atoms are not the smallest in the world cause the objects in them are smaller.

VashaNatasha [74]

Answer:

Electronic measurement tools accurately store a large volume of data very quickly.

Explanation:

Electronic measurement tools are important devices used in taking records of data. They are very good measuring tools because they can measure a large amount of data very quickly and in a very precise manner. Examples include; multimeters, voltmeters, oscilloscopes, etc.

Their sizes might vary but a general attribute to them all is the speed at which data is recorded and the precision with which they are measured. Scientists most times use these devices to take measurements.

inn [45]
Yaya says:
 IQ Scores have a bell-shaped distribution with a mean of 100 and a standard deviation of 15. What percentage of IQ scores are between 70 and 130?

<span>Solution: </span>130 – 100 = 30 which is 2(15). Thus, 130 is 2 standard deviations to the right of the mean. 100 – 70 = 30 which is 2(15). Thus, 70 is 2 standard deviations to the left of the mean. Since 70 to 130 is within 2 standard deviations of the mean, we know that <span>about 95% of the IQ scores would be between 70 and 130.</span>
