Answer:
Explanation:
Given that:
A cyclist rides 4.0 km due west, then 12.0 km 33° west of north. From this point she rides 9.0 km due east.
Let:
Assuming that:
east is the + x axis and has a unit vector of
north is the +y axis and has a unit vector of
west is the - x axis and has a unit vector of
south is the - y axis and has a unit vector of -
The displacement in a given direction of x can be expressed by the formula:
The displacement in a given direction of y can be expressed by the formula:
The final displacement can be expressed by the relation;
Palisade mesophyll layer
The palisade mesophyll layer is made up of closely-packed, elongated cells located just below the upper epidermis. They contain chloroplasts and carry out most of the photosynthesis. Hope this helps!

Explanation:
Answer:
the spring constant is -89.2857 n/m
Explanation:
The computation of the spring constant is shown below:
As we know that
Force in newtons = Spring constant × amount of extension
F = -k × x
where
F = 25 N
And, x = 0.280m
So, the spring constant would 2
= 25N ÷ 0.280 m
= -89.2857 n/m
Hence the spring constant is -89.2857 n/m
