Reference point is the answere
Since the light travels in the vacuum then its velocity will be C=3*10^8 m/sec.....then you will convert it to secs=28000*365*24*60*60=8.83008*10^11
then v=s/t then s=v*t=(3*10^8)(8.83008*10^11)=2.649024*10^20 meters

This brightly colored fish is native to the Indo-Pacific from Australia north to southern Japan and south to Micronesia. The lionfish is usually found in coral reefs of tropical waters, hovering in caves or near crevices. Native regions as well as Savannah, Georgia; Palm Beach and Boca Raton, Florida; Long Island, New York; Bermuda and possibly Charleston. In southern Florida and off the coast of the Carolinas in early to mid 1990s.

Answer:
True
Explanation:
Electronegativity difference of less than 0.4 characterized covalent bonds. For two atoms with an electronegativity difference of between 0.4 and 2.0, a polar covalent bond is formed-one that is neither ionic nor totally covalent.
<h3><u>Answer</u>;</h3>
<u>D. 11.8 m/s</u>
<h3><u>Explanation;</u></h3>
Using the equation;
v = u + at; such that v is the velocity attained, u is the initial velocity and a is the acceleration;
In our case, acorn falling from a tree is described as free fall aided by gravity;
Therefore, initial velocity is zero, u = 0, and the acceleration is due to gravity, thus, a = 9.8 m/s² , t = 1.2 seconds
Thus;
The equation becomes;
v = gt , since; u =0, and a = g = 9.8 m/s²
v = 9.8 × 1.2
= 11.76 m/s
<u> ≈ 11.8 m/s</u>
