Mr. spoke is travelling with speed v = 9.4c.
Mr. spoke is apparently unknowing of theory of special relativity by Einstein. The theory states that moving clock tick slower than stationery clock.
Time elapse =∆t = 3 weeks
(In earth stationery frame)
Time ellipse= ∆t' = 1 week
(In the frame of rocket)
∆t' = ∆t'/γ
1/y² = 1 - v²/c²
∆t'²/∆t² =
=1²/3²
=1/9
c= 3×10⁸m/s
on solving above equation we get :
v = 9.4c
He was spreading around at close to the speed of light.
Experience significant time dilatation.
He is travelling with speed v = 9.4c.

if i am correct the answer is d. because depending on how far a wavelength goes we see different colors.
Speed = 500m/5min = 100 m/min. Direction = west. Velocity = 100 m/min west.
No it does not have a timing belt
The smallest number of products in a decomposition reaction is two because there is 1 reactant that breaks down and when it does break down there must be two products. It is generally more, though.
