Answer:

-110 N

Explanation:

Una carga de 50 N unida a un resorte que cuelga verticalmente estira el resorte 5cm. El resorte se coloca ahora horizontalmente sobre una masa y se estira 11cm. ¿Qué fuerza se requiere para estirar ese resorte en esa cantidad?

Solution:

La constante de resorte (k) es la relación entre la fuerza (F) y la extensión (d) como resultado de la fuerza aplicada, por lo tanto:

k = F / d

Dado que F = 50 N, d = 5 cm = 0.05 m. Por eso:

k = F / d = 50 N / 0.05 = 1000 N / m

La fuerza (F) requerida para provocar un estiramiento de 11 cm se da como:

F = -kx

x = 11 cm = 0,11 m. Por eso:

F = -kx = -1000 * 0,11 = -110 N

El signo negativo significa que el objeto se tira hacia el resorte.

The role of pigments in the photosynthesis reaction is to
pashok25 [27]

Answer:

Option A, Start the reaction by absorbing light energy

Explanation:

Chlorophyll is a green color pigment in plant that helps in entrapping sunlight. Being green in color, it absorbs the blue and red light and reflects the green light. The molecules of chlorophyll gains energy from sunlight and then jumps to higher energy levels by the process known as photo excitation. These excited molecules get ionized to further initiate the process of photosynthesis.

Hence, option A is correct.

Which graph représents selection that may lead to reduced variatior
rewona [7]

The SECOND graph represents selection that may lead to reduced variation. It is an example of stabilizing selection.

<h3>What is Stabilizing selection?  </h3>

Stabilizing selection is a type of natural selection that leads to a  decrease in the genetic variation of the population.

In Stabilizing selection, natural selection tends to favor an average phenotype and then can remove (select) extreme variations.

Stabilizing selection generates a modified bell curve graph in which the central portion is narrower and it is taller than the normal distribution bell shape.
