Why was England most successful in colonizing America? The English that settled the middle colonies of New York and Pennsylvania found good farmland that was great for growing food that could be sold in Europe. Finally, the English that colonized the southern colonies found that area was good for growing cash crops like tobacco. What […]
How many full moons are there in 100 years?
How many full moons are there in 100 years? Most years have 12 Full Moons, one each month. However, our calendar is not perfectly synchronized with astronomical events. Therefore, now and then, a year has 13 Full Moons. When this happens, at least one of those Full Moons is called a Blue Moon. How is […]

What is the basis of stratigraphy?
What is the basis of stratigraphy? Stratigraphy, scientific discipline concerned with the description of rock successions and their interpretation in terms of a general time scale. It provides a basis for historical geology, and its principles and methods have found application in such fields as petroleum geology and archaeology. What is the law principle of […]
What is the final product of cellular respiration?
What is the final product of cellular respiration? ATP What is produced through cellular respiration? During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called […]
What is a muscle moment arm?
What is a muscle moment arm? The moment arm of a muscle force is defined by the perpendicular distance between the muscle’s line of action and the instantaneous centre of rotation of the joint in which it spans, and represents the capacity of that muscle to exert a joint torque (Pandy, 1999). Does a longer […]
Why do we use resistors?
Why do we use resistors? A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. What causes resistors to burn? Blowing Up a […]
Which installation is not covered by the NEC?
Which installation is not covered by the NEC? The NEC does not cover electrical installations in ships, water- craft, railway rolling stock, aircraft, or automotive vehicles. What is the purpose of the NEC? The NEC (the National Fire Protection Association’s NFPA 70) is a widely-adopted model code for the installation of electrical components and systems. […]
How fast do planes fly in mph?
How fast do planes fly in mph? The typical cruising airspeed for a long-distance commercial passenger aircraft is approximately 880–926 km/h (475–500 kn; 547–575 mph). Was the mosquito faster than the Spitfire? During its trials on 16 January 1941, W4050 outpaced a Spitfire at 6,000 ft (1,800 m). The original estimates were that as the […]
Why are telescopes limited?
Why are telescopes limited? The resolution of an optical imaging system – a microscope, telescope, or camera – can be limited by factors such as imperfections in the lenses or misalignment. Is the human eye diffraction limited? The human eye is close to being fully diffraction-limited, at least for photopic (cone-based) vision at the center […]
