Why is e = hv important in pv cell considerations?

Biology
1 answer:
Zanzabum3 years ago
8 0
E=hv is an equation important when dealing with light. E refers to the energy of a photon; h is Planck's constant and v is the wavelength. According to this equation, light particles called photons travels in packets of energy. This is important in pv cells because this is the technology used to harness solar energy which is converted to electricity. The amount of energy should be estimated to know the appropriate material of construction of the pv cell to achieve optimum conditions. In this way, the pv cell could maximize the sun's energy.

How could the tomato plants response to being eaten by a hornworm caterpillar be described as a function of homeostasis
sesenic [268]

Answer:

First, it's important to get clear on the meaning of Homeostasis.

In simple terms, it refers to the capacity of a living thing (plant or animal) to react or behave in such a way that enables it to continue to survive irrespective of changes in its immediate environment.

       

Explanation:

In humans, the body has a system which reacts to the external stimuli of temprature. When the weather is hot, the brain through a sequence of electrical and chemical signals tells the skin to open up the pore, then we experience venting of sweating which cools the body and regulates internal heat. This is an instance of homeostasis.

This does not mean that the plant or animal is completely immune to such external changes.

In the case of the tomato plant, the hair on the leaves and stem of the plant is an example of Homeostatic responses which have evolved over the years to discourage predators such as the hornworm caterpillar from defoliating the plant.

Cheers!

How do veins keep blood moving
GenaCL600 [577]

Answer:

The return of blood to the heart is assisted by the action of the skeletal- muscle pump. As muscles move, they squeeze the veins running through them. Veins contain a series of one-way valves, and they are squeezed, blood is pushed through the valves, which then close to prevent backflow.
