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.
Answer: B (130)
Explanation:
A trapezoidal Riemann sum can be found by multiplying the width (the change in x) of each sub interval by the average of the y values of the two points at either end of the section and then adding up all of the sun intervals. Therefore, the trapezoidal approximation would equal 0.5(40) + 1.5(50) + 1(35) to get the answer of 130.
