I'm having trouble completing the problem I've attached a picture of below. I was able to find the the Earth's average speed in m/s relative to the sun by doing (2pi*(1.49x10^11))/31536000. But I am struggling to find the average velocity for the same thing over a period of one year in m/s. I was wondering how to calculate that? I've tried doing the (final velocity-initial velocity)/2 but the program doesn't accept my answer when using that approach.
Suppose the Sun were somehow replaced by a star with five times as much mass. How long would the Earth year last in this last case? (hint: Newton’s version of Kepler’s 3rd Law)
1Which of the following best describes a frame of reference?
an experiment that proved that Earth did not have an aether wind
the theory that describes the behavior and characteristics of objects moving at relativistic speeds
the effect of the slowing of time as an object moves with high speeds
a point in which someone relates the behavior of an object from one perspective
2If an electron moves from n = 5 to n = 1, what wavelength of light is emitted? (h = 6.626 x 10-34, 1 eV = 1.6 x 10-19 J)
