In this item, we are asked to determine the speed of the bobsled given the distance traveled and the time it takes to cover the certain distance. This can mathematically be expressed as,
speed = distance / time
Substituting the given values in this item,
speed = (113 m) / (29 s)
speed = 3.90 m/s
<em>ANSWER: 3.90 m/s</em>
Answer:the force is needed to stretch it farther.
Explanation: the definition of force is push or pull so imagine stretching a rubber band your pulling the band which means you increase the force.

Answer:
X2 - X2'=3.24×10⁻⁴m
Explanation:
Given Data
λ1=730nm=
λ2=640nm
d=0.61 mm
D=1.1 m
Distance of the second bright fringe from the central fringe is given by
Xn = = D x n x2 λ / d
X2 = 2 D λ1 / d
X2' = 2 D λ2 / d
Separation between the second bright fringes of the two wavelengths ( the separation between the second order fringes ) is ,
X2 - X2' = 2 D ( λ1 - λ2 ) / d
X2 - X2'= {2 x 1. 1 (730×10^-9 - 640×10^-9) }/ 0.61 x 10 ^-3
X2 - X2'=3.24×10⁻⁴m
