Answer:
Explanation:
Stomata are tiny openings or pores that enable gaseous exchange. Stomata are usually found in plant leaves, but they can also be found in some stems. When it does not need carbon dioxide for photosynthesis, the plant closes these pores. The stomata in plants are enclosed by bean shaped cells called guard cells.

Question :
An object travels 20m in 4s and then other 20m in 10s . What is the average speed of the object ?
Solution :
As per the question we have two cases so let's assume each as Case 1 and Case 2 respectively !
Case 1 :
Distance Covered : 20m
Time taken : 4 sec
Speed : Distance / time
: 20 / 4
: 5 m / sec
Case 2 :
Distance Covered : 20 m
Time taken : 10 sec
Speed : Distance / time
: 20 / 10
: 2 m / sec
huge average speed = total distance total time
averagespeed=totaltimetotaldistance
= \5 + 2 4 + 10=4+105+2
= 7 40 = 0.175=407=0.175
Hence , the average speed of the object is 0.175 m / sec !!
