D. The plant can’t reproduce.
The reason a plant has a flower is for reproduction. The attractive smell and color of the flower attract pollinators. These pollinators eat nectar from the flower and get covered in pollen. They then transport the pollen to other flowers were the pollen is used by the other plant to produce seeds. The seeds are the way that the plant reproduces. Option A) doesn’t make sense because absorbing water is done by the roots. Option B) doesn’t make sense because that is done in the plants leaves. And C) doesn’t make sense because the plant supports itself using the stem. So the answer must be D)

g A cylinder of mass m is free to slide in a vertical tube. The kinetic friction force between the cylinder and the walls of the

sdas [7]

Answer:

The vertical distance is $d = \frac{2}{k} *[mg + f]$

Explanation:

From the question we are told that

The mass of the cylinder is m

The kinetic frictional force is f

Generally from the work energy theorem

$E = P + W_f$

Here E the the energy of the spring which is increasing and this is mathematically represented as

$E = \frac{1}{2} * k * d^2$

Here k is the spring constant

P is the potential energy of the cylinder which is mathematically represented as

$P = mgd$

And

$W_f$ is the workdone by friction which is mathematically represented as

$W_f = f * d$

$\frac{1}{2} * k * d^2 = mgd + f * d$

=> $\frac{1}{2} * k * d^2 = d[mg + f ]$

=> $\frac{1}{2} * k * d = [mg + f ]$

=> $d = \frac{2}{k} *[mg + f]$
