Answer:
Explanation:
This question appears incomplete. However, one of the main differences (in organelles) between plants and animal cells is the absence of cell wall and chloroplast in animal cells while both organelles are present in plant cells. The cell wall is outside of the cell membrane. The cell wall provides rigidity and support to the plant cell while the chloroplast is the cellular "machinery" for photosynthesis. The chloroplast contains the green pigment called chlorophyll which provides green plants with there colour and assist the plants in absorbing/capturing of sunlight/energy for the purpose of photosynthesis (self production of food by green plants).
Answer:
10 m/s/s or m/s²
Explanation:
Acceleration can be calculated by using the formula;
a = v - u/t
Where;
a = acceleration (m/s²)
v = final velocity (m/s)
u = initial velocity (m/s)
t = time (s)
In other terms, acceleration (a) can be represented as ∆V/t.
According to this question, a ball accelerates from 10 m/s (u) to 30 m/s (v) in 2 seconds. Hence, the acceleration of the ball is as follows:
a = 30 - 10/2
a = 20/2
a = 10m/s².
I believe it would be option A. If it still doesn't answer your question, don't hesitate comment below. :)
