Why does MacCready make a model and take it to the swimming pool? [MacCready] went so far as to make a mini model of the Condor, which he flew around in a swimming pool in order to better understand the effects of air mass on the square wing with respect to making turns. What was […]
What are 3 properties of magnesium carbonate?
What are 3 properties of magnesium carbonate? Magnesium carbonate is a basic hydrated magnesium carbonate or a normally hydrated magnesium carbonate. It occurs as light, white, friable masses or as a bulky white powder. It is odourless and is stable in air. It is practically insoluble in water to which however it imparts a slightly […]
What are 3 types of glacial erosion?
What are 3 types of glacial erosion? Glaciers were formed which move down valleys with great erosive power. These glaciers carved new scenery. There are three main types of glacial erosion – plucking, abrasion and freeze thaw. Plucking is when melt water from a glacier freezes around lumps of cracked and broken rock. What are […]

How is a scientific law formed?
How is a scientific law formed? Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. Laws are developed from data and can be further developed through mathematics; in all cases they are directly or indirectly based on empirical evidence. What are […]
What happens when a charged particle enters a uniform magnetic field?
What happens when a charged particle enters a uniform magnetic field? The simplest case occurs when a charged particle moves perpendicular to a uniform B-field (Figure 11.4. 1). The magnetic force is perpendicular to the velocity, so velocity changes in direction but not magnitude. The result is uniform circular motion. When a charged particle enters […]

What are the basic components of textile fabrics?
What are the basic components of textile fabrics? Textiles are made from many materials, with four main sources: animal (wool, silk), plant (cotton, flax, jute, bamboo), mineral (asbestos, glass fibre), and synthetic (nylon, polyester, acrylic, rayon). The first three are natural. In the 20th century, they were supplemented by artificial fibres made from petroleum. What […]
