Answer:
Ultraviolet radiation would yield more electrical energy
Explanation:
The reason for the ultraviolet to generate more energy is that there would be getting more electrons per unit of time the photovoltaic cell, due to the higher frequency of the ultraviolet in comparison with the infrared radiation.
The infrared spectrum goes from 300 GHz (10^9 Hertz) to 400 THz or (10^12 Hertz).
The ultraviolet spectrum goes from 800 THz to 30.000 THz or (10^12 Hertz). This kind of radiation is responsible for skin burn from the sun and it´s the “ most usable” part from the sunlight in a photovoltaic cell.
Answer:
No,it isn't concave. The correct answer is convex lens.
Explanation:
<em>A lens is a piece of transparent material bound by two surfaces of which at least one is curved. A lens bound by two spherical surfaces bulging outwards is called a bi-convex lens or simply a convex lens. A single piece of glass that curves outward and converges the light incident on it is also called a convex lens.</em>
The variables that Madison will have to deal with to test her hypothesis that increased concentrations of salt in the air speeds the corrosion of certain metals are as follows:
- Independent variable: concentration of salt
- Dependent variable: corrosion of metal
<h3>What are independent and dependent variables?</h3>
In an experiment, the independent variable is the variable that is changed or manipulated in a series of experiments.
On the other hand, a dependent variable is that outcome measured to see the effectiveness of the treatment.
According to this question, Madison makes an hypothesis that an increased concentrations of salt in the air speeds the corrosion of certain metals, the variables she should look out for are as follows:
- Independent variable: concentration of salt
- Dependent variable: corrosion of metal
