As an airplane is taking off at an airport its position is closely monitored by radar. the following three positions are measured with their corresponding times: x1 = 135.94 m at t1 = 3.20 s,
x2 = 169.39 m at t2 = 3.70 s,
x3 = 206.88 m at t3 = 4.20 s.
what is the acceleration of the airplane at t2 = 3.70 s? (assume that the acceleration of the airplane is constant.)

Ahypothesis is? close agreement by competent observers of observations of the same phenomena. a guess that has been tested over and over again and always found to be true. an educated guess that has yet to be proven by experiment. the long side of a right triangle. a synthesis of a large collection of information that includes guesses.

Starting with only the balmer series light (visible light), how could we ensure that the solar panels generate a current that mark can use for his power station? a)by gradually increasing the brightness (amount) of light that we shine on it. b)by gradually increasing the frequency of the light we shine on it. c)by gradually increasing the wavelength of the light that we shine on it.
