In franklin's diffraction image measure the vertical distance between the 5th and oth layer lines. the original size of the image (disc diameter) was 9.4 cm. the distance between fiber and film was 9 cm. for diffraction, franklin presumably used the ka line of copper (0.15 nm). from your measurèment and the parameters above, calculate the helical pitch. explain how you arrived at your conclusion

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.

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.

The law of reflection states that the angle of reflection is equal to the angle of
