The diffraction f light passing through a narrow opening, provides evidence that light has a wave nature.
To find the net charge you take the number of protons and subtract the number of electrons, and the answer will be your charge.
This atom has 11 electrons AND 11 protons
11 - 11 = 0 net charge
The first one accelerate at 2m/s
the second one accelerates at 1.6666m/s
therefore statement b. the 10kg object is your answer
hope this helps :)
Answer: - 0.75 m
Explanation: The displacement will be the sum of the slope of the graph within the given time. From time 8s to 16s, the slope m will be; Slope = (15 - 6) / (16 - 8) Slope = 9 / 8 From time 16s to 24s Slope = (15 - 0) / ( 16 - 2 Slope = -15 / 8 Displacement = 9/8 - 15/8 Displacement = -6/8
Displacement = - 0.75 m
