Are any goods perfectly elastic? If demand is perfectly elastic, it means that at a certain price demand is infinite (A good with a very high elasticity of demand). In other words, if a firm increased the price by 1%, it would see all its demand evaporate. Is coffee elastic or inelastic? Availability of Substitutes […]
What is center of projection?
What is center of projection? The center of projection is the origin or source of the stream of projecting rays. Depending on the distance between the center of projection and the image plane, the distinction should be made between central (conical) projections and parallel (cylindrical) projections. What is foreshortening factor? 3) The ratio of projected […]
Do tents attract lightning?
Do tents attract lightning? Tents alone don’t attract lightning, but that doesn’t mean they’re safe during a thunderstorm. The possibility for a tent to get struck by lightning is increased by the campsite location and adjacent tall objects. What happens if lightning hits a tent? If a lightning bolt hits a tent the energy will […]
What are interference colors?
What are interference colors? Definition. Liquitex® Interference Colours are colourless, transparent paints made from titanium coated mica flakes rather than traditional pigments. They are also known as “Opalescent Colours.” They change their colour (exhibiting a metallic look and colour shift) depending upon the viewing angle. What causes interference colors? Interference Colors Produced by Polychromatic Light […]

What role does carbon dioxide play in photosynthesis?
What role does carbon dioxide play in photosynthesis? The carbon dioxide enters the leaves of the plant through small pores called stomata. The plant uses sunlight as energy to perform this chemical reaction. Photosynthesis separates carbon dioxide and water — known as CO2 and H2O, respectively — into their individual molecules and combines them into […]
Can 2 remote control cars same frequency?
Can 2 remote control cars same frequency? If you don’t plan to run your RC cars, trucks, boats, or aircraft alongside other radio controlled vehicles, it doesn’t really matter which frequency they use. However, running two 27MHz or two 49MHz RC cars near each other will usually result in interference—crosstalk. The radio signals get mixed […]
What forces act on a person jumping?
What forces act on a person jumping? Part II: The Jump Whether you are standing or jumping, the only external forces acting on your body are the normal force from the ground and gravity. How can you jump? Raising your center of mass into the air seems like it would require gravity to diminish or […]
What is the difference between membrane potential and resting potential?
What is the difference between membrane potential and resting potential? For a cell’s membrane potential, the reference point is the outside of the cell. Because there is a potential difference across the cell membrane, the membrane is said to be polarized. If the membrane potential becomes more positive than it is at the resting potential, […]
Are magnets bad for automatic watches?
Are magnets bad for automatic watches? Analog quartz watches utilize the power of magnetic force in order to drive the step motors to move the rotors. As a result, watches may stop or fail to keep correct time. But magnetism remaining inside of the watch does not affect its accuracy, so keep it away from […]
