Answer:
Measurement is important so we could measure certain things right. By taking measurements we can have a knowledge of sizes, lengths, widths etc.
Explanation:
Answer:
Explanation:
Using second degree taylor polynomials
let
be position function and set 
where S(0) is the initial position
Then
and 
we have
, 
so 
b.) yes
The transit method requires watching the light output of a star over long periods of time. A transit occurs when the planet crosses in front of its star from earths point of view. Since there is a small object (the planet) now blocking some of the star, it appears to dim a little bit for a while until the planet passes. If we are in a position where that occurs regularly (most paths of planets do not happen to be on the line of sight between earth and their star) we can deduce the period of orbit. From the amount of dimming and the period you can estimate the mass
Part A
Free fall motion
h = 3.1 m
Equation: Vf = √(2gh) = √(2*9.8 m/s^2 * 3.1 m) = 7.8 m/s
That is the only part in the question.
