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.
420x6/7 = 360 starting amount
420-360 = 60 interest
60/360 = 16.67%
Answer:
The outer layer of the star expands
Explanation:
Late in life, when the hydrogen fuel for nuclear fusion is exhausted, the core of the star tends to collapse. That process generates heat that pushes the outer layers of the star outward.
The outer layer of the star expands.
Assuming we don't know the speed capabilities of the tractor, the time it would take simply be the rate in miles per hour. It has a direct correlation between speed and time spent, so the miles the tractor needs to plow is unneeded.
