= 156 hours
Solar ovens use heat from the Sun to cook food. They work on a principle similar to that of solar panels used to heat homes. What characteristics will your ovens need so that they absorb and retain heat from the Sun? You can do research on the Internet if you wish.
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.

Technician A says that valve stem height should be checked and the top of the valve ground, if necessary. Technician B says that an incorrect valve stem height may hold the valve open. Which technician is correct
Answer:
Technician A only
Explanation:
The valve stem height is important as the effects of incorrect valve stem height includes;
1) Side thrust
2) Highly recessed valve
3) Effect on the geometry of the combustion chamber
4) Changes in the volume of the combustion chamber
5) The amount of lifter preload
6) The spring height
7) The amount the valve lifts above the valve seat
8) The valve life span
The valve may stay open after the camshaft lobe is moves past the under the lifter when a valve float occurs at high engine speeds
The valve tips can be grinded as recommended by the manufacturer to correct the the valve stem height.

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.

Architectural engineering, also known as building engineering or architecture engineering, is an engineering discipline that deals with the technological aspects and multi-disciplinary approach to planning, design, construction and operation of buildings, such as analysis and integrated design of environmental systems (energy conservation, HVAC, plumbing, lighting, fire protection, acoustics, vertical and horizontal transportation, electrical power systems), structural systems, behavior and properties of building components and materials, and construction management.[1][2]
From reduction of greenhouse gas emissions to the construction of resilient buildings, architectural engineers are at the forefront of addressing several major challenges of the 21st century. They apply the latest scientific knowledge and technologies to the design of buildings. Architectural engineering as a relatively new licensed profession emerged in the 20th century as a result of the rapid technological developments. Architectural engineers are at the forefront of two major historical opportunities that today's world is immersed in: (1) that of rapidly advancing computer-technology, and (2) the parallel revolution arising from the need to create a sustainable planet.[3][4]
Distinguished from architecture as an art of design, architectural engineering, is the art and science of engineering and construction as practiced in respect of buildings.[5]
