How do you explain pressure altitude? Pressure altitude is the attitude displayed on the altimeter when the Kollsman window is set to 29.92 inches of mercury, or 1013.4 millibars. Pilots cannot use pressure altitude below 18,000 feet, because then the aircraft’s true altitude would change depending on temperature. Why do we calculate pressure altitude? Pressure […]
What are ferromagnetic and antiferromagnetic materials?
What are ferromagnetic and antiferromagnetic materials? Ferromagnetic materials have magnetic moments that align parallel to the applied magnetic field whereas antiferromagnetic materials have antiparallel magnetic moments. Therefore the magnetic moments still cancel each other out and the overall magnetization is zero. What is hysteresis loop explain with diagram? A hysteresis loop shows the relationship between […]
Why does massless light bend near a large mass?
Why does massless light bend near a large mass? Light can form a curve if it travels near a big mass. You are right, photons don’t have mass. You are also right, photons doesn’t follow Newton’s gravitation law. Photons can be pulled by gravity not because of their mass (they have none) but because gravity […]
What is periodic table and its properties?
What is periodic table and its properties? The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. What are two characteristics of elements? All elements have […]
Does a force meter measure weight?
Does a force meter measure weight? The weight of something (or someone) is the force caused by the pull of gravity on the mass of something (or someone). Weight is measured in Newtons (N) and is named after Sir Isaac Newton, who discovered gravity. A force meter (or Newton meter) is used to measure weight. […]

What is called critical angle?
What is called critical angle? When the angle of incidence in water reaches a certain critical value, the refracted ray lies along the boundary, having an angle of refraction of 90-degrees. This angle of incidence is known as the critical angle; it is the largest angle of incidence for which refraction can still occur. Why […]

What are the 3 functions of roots?
What are the 3 functions of roots? Root, in botany, that part of a vascular plant normally underground. Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods. What are the four functions of roots? The functions of root […]
How long does it take to become a solar engineer?
How long does it take to become a solar engineer? These workers typically need a high school diploma, but some take courses at a technical school or community college; they also receive on-the-job training lasting up to 1 year. Some PV installers learn to install panels as part of an apprenticeship. Is solar installation a […]
