What is the role of science and technology in development? Science and technology (S) capabilities are fundamental for social and economic progress in developing countries; for example, in the health sector, scientific research led to the development and introduction of oral rehydration therapy, which became the cornerstone of international efforts to control diarrheal … What […]

Why is AXE a wedge? It changes the direction of a downward force to a sideways force. As the hammer hits the wedge the downward force is changed to a sideways force pushing the object that the wedge is embedded into sideways. An axe is an example of a wedge as is any sharp instrument […]

What is the meaning of building physics? Building physics is the application of the principles of physics to the built environment. Building physicists bring a fundamental understanding of physics to improving the design of building fabrics and surrounding spaces. What is construction physics? Construction Physics is a theory-based understanding of construction processes under a flow […]

What is br2 called? Bromine What Colour is bromine? reddish brown What’s the name for br2? What is the shape of Br2? Regarding the polarity of Br2, you must read out an article on the polarity of Br2. Due to the presence of atoms of the same element, the molecular geometry of Dibromine is Linear […]

How do you get sensible heat? Sensible heating Btu is measured by the ageless formula CFM x Delta-T x 1.08. To measure heating Btu, multiply the measure supply airflow (in cfm) by the temperature change from the average supply register temperature to the average return grille temperature, and multiply this total by the formula constant […]

What is Pseudostratified epithelial tissue? A pseudostratified epithelium is a type of epithelium that, though comprising only a single layer of cells, has its cell nuclei positioned in a manner suggestive of stratified epithelia. How does simple cuboidal epithelium absorb? Absorption The proximal convoluted tubules and distal convoluted tubules in the kidneys, lined with the […]

How much HP does a alternator use? An alternator typically takes about 1 HP (horse power) for every 25 amps of power generated. So, a 100 amp alternator will require about 4 HP at full output. Most alternators do not operate at full output for very long. Is 200 amp alternator enough? Also, cables, distance, […]

How does a light ray travels? If you shine a beam of light (a bundle of parallel rays) through the air, it will travel in a straight line. Rays of light usually travel in straight lines until they hit something. The bending of a ray of light also occurs when the ray comes out of […]

Is 125 over 80 a good blood pressure? Normal – Systolic is less than 120 AND diastolic is less than 80. Elevated – Systolic is 120 – 129 AND diastolic is less than 80. High Stage 1 – Systolic is 130 – 139 OR diastolic is 80 – 89. High Stage 2 – Systolic is […]

What is the principle of parallel plate capacitor? The capacitance of an insulated conductor is increased by bringing an uncharged earthed conductor near it. An arrangement of two conductors carrying equal and opposite charge separated by a dielectric medium are said to form a capacitor. What is the basic principle of the capacitor? A capacitor […]
