On oct 14, NYC will see the sun eclipsed about ____ % _____ than Burlington - correct answer 6, more Because of the moons eccentric orbit, the maximum change in its apparent diameter is closest to ____ % - correct answer 10 The sun usually looks redder at sunset than at midday because ____ - correct answer you're looking through a longer path of atmosphere at sunset than at midday Annular solar eclipses cannot be seen - correct answer when the moon is near its perigee On average, th...

Describe the relationship between the frequency, wavelength, and velocity (speed) of a wave. - AnswerThe more times the wave is passing through a point in space = a higher frequency, the higher frequency creates a smaller wavelength, which is why the smallest wave is a gamma wave, it has the highest frequency and the shortest distance between waves, the velocity can be measured in m/s and is composed of frequency and wavelength Calculate any one (frequency, wavelength, or velocity) given the...

Why are alpha particles deflected by the nucleus? - Answer-Because both the alpha particles and the nucleus are positively charged and so the alpha particle is repelled. Is this statement (Dalton's Theory) true or false and why? "All atoms of an element are identical and have the same mass and properties." - Answer-False. Atoms of the same element can have different numbers of neutrons. What is the evidence that electrons are subatomic particles? - Answer-The nature of the electron is i...
