Riddle of the Day:
A high-density particle lies at the origin of a Cartesian plane. An electron orbits around the particle at X^2 + Y^2 = D. Take the particle to be massless and a point.
Let t be the amount of time
When t = 0, the electron lies at the x axis.
The value of D is given as follows: D = 106.9(0.69)^t -6.9 and D>0
Given that the electron orbits counter-clockwise at a rate of one second per successive phase, meaning 1 round per second,
a) i)find the value of when the electron strikes the particleii) if a Tangent were to be drawn at the incidence of the point at which the electron strikes the particle, find the gradient of that tangent of incidence.
