Answer:
Sugars...
Explanation:
Several meteorites have been found to carry molecules of sugars that are essential for life. These sugars include Ribose, Arabinose and Xylose. These are found in meteorites that are rich in carbon. These significant discoveries can pave way in finding the origin of life on Earth.
The water has an irregular surface so if the light rays fall on top then it will reflect oppositely or in some cases may refract, so the fish will seem a bit smaller or further or closer in anyway, example if u put a straw in water it looks bent but is it ? nope. So the main reason is that it refracts which makes the accuracy lesser which make it difficult.
Answer:

Explanation:
The acceleration of an object is given by

where
v is the final velocity
u is the initial velocity
t is the time it takes for the velocity to change from u to v
For the boat in the problem,
v = 10 m/s
u = 0
t = 2 s
Substituting, we find the acceleration

9.8 m/s^s and thats the earths gravitational force!
Hope it helps
Answer:
V=16.306m/s
Explanation:
Use V=vi+at
So V= 7.29m/s+(3.22)(2.8s)= 16.306m/s
