Acceleration = (change in speed) / (time for the change)
Change in speed = (New speed) - (old speed)
Change in speed = (0.8 m/s - 0.5 m/s) = 0.3 m/s
Time for the change = 3 seconds
Acceleration = (0.3 m/s) / (3 s)
<em>Acceleration = 0.1 m/s²</em>

C. 7, 5 solar and 2 lunar eclipses or 2 solar and 5 lunar eclipses
Answer:
A, molecules
Explanation:
Molecules were viewable around the time period of the computers shown on the screen
Answer:
y (lambda) = c / f incident wavelength
y = 3 * E8 / 2.4 * E9 = .125 m incident wavelength
y' = .125 / 1.45 = .0862 m wavelength inside of tray
T = y' / 4 thickness required for phase change at bottom
T = .0862 m / 4 = .0261 m = 2.61 cm
