Explanation:
Absorption of the sun's energy (heat) in solar cooking is best achieved when a surface is dark in color, thus the most common solar oven interiors are usually black in color as well as the color of the cookware used for cooking the food. Dark colors absorb the heat, whereas light colors do not absorb heat well.
Metal reflectors should be positioned around the oven to maximize light input to be the most effective.
The characteristics that will ovens need, so they absorb and retain heat from the Sun, are metal reflectors that should be placed around the oven to maximize light input.
What is solar energy?Solar energy is defined as sun-derived energy. Energy can be converted to electricity using solar energy technologies such as solar panels, or it can be used directly to heat and light homes.
There are other renewable energy sources that are also important to us. We have tidal, hydropower, biomass, and wind, for example.
Absorption of the sun's energy (heat) in solar cooking is best achieved when a surface is dark.
Thus, the most common solar oven interiors, as well as the color of the cookware used to cook the food, are usually black. Light colors do not absorb heat well, whereas dark colors do.

The technique of using guidelines and reference points
to create a realistic sense of depth in a two-dimensional
artwork is called
Answer:
Linear perspective.
Explanation:
The technique of using guidelines and reference points to create a realistic sense (illusion) of depth in a two-dimensional artwork is called linear perspective.
In linear perspective, the realistic sense (illusion) of depth is typically created or done on a flat surface so that all the orthogonal or parallel lines can converge at a single vanish point of the drawing's horizon line. Thus, this technique make drawings or paintings of objects to look real.
Hence, linear perspective comprises of three (3) basic components and these are;
1. Vanishing point.
2. Horizon line.
3. Orthogonal or parallel lines.
Generally, drawings (objects) that are drawn or created using linear perspective appear to be larger when viewed closely while drawings (objects) that are further away, appear to be small.
