Answers
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities.

Answer:
Answer is (1/2) m/s²
Explanation:
Initial velocity,u = 36km/h = 36 X 1000 m
--------------- = 10m/s
3600 s
Final velocity,v = 54km/h = 54 X 1000 m
--------------- = 15m/s
3600 s
t = 10s
Acceleration,a = v - u 15m/s - 10m/s
------- = --------------------
t 10s
a = 5m/s
--------
10s
a = (1/2) (m/s)/s
a = 1/2 m/s²
