What are the main parts of electric motor? Different Parts of an Electric Motor and Their Function A power supply – mostly DC for a simple motor. Field Magnet – could be a permanent magnet or an electromagnet. An Armature or rotor. Commutator. Brushes. Axle. What are 3 parts of an electric motor? No matter […]

How far can you kick a ball? While some weaker placekickers may have trouble kicking field goals longer than 30 yards (making field goals from beyond the 13 difficult), others may consistently make 50-yarders, making it practical to kick from beyond the 33. For most NFL kickers, the 35-yard line is typically the limit of […]

Which one has a higher electrical resistance a 100 watt bulb or a 60 watt bulb? A 60-watt bulb has a higher electrical resistance than a 100-watt bulb. Because power is inversely proportional to resistance, when the power is less, the resistance is high. Which one is having lesser resistance a 220v 60W bulb or […]

What does 50% lung capacity mean? Likewise, if your FEV1 is 50%, your lungs are able to handle only half as much air as they should. If your FEV1 is 33%, your lungs are able to handle even less—only a third as much. The lower your FEV1 percentage, the less air your lungs are able […]

How high can a balloon go? Because density is altered by altitude, the helium balloon can reach a height of 9,000 meters, or 29,537 feet. Anything higher than this altitude will cause the helium within the balloon to expand and the balloon to pop. What is the common unbalanced force acting on an object in […]

How many electrons can cytochrome c accept? one electron What happens if cytochrome c is inhibited? Cyanide, azide, and carbon monoxide all bind to cytochrome c oxidase, inhibiting the protein from functioning and leading to the chemical asphyxiation of cells. NO and CN− will compete with oxygen to bind at the site, reducing the rate […]

How did Brahe actually die? The famed 16th century Danish astronomer and mathematician Tycho Brahe was long assumed to have died from poisoning. Recently, archaeologists pored over his skeleton to reveal the real cause of his early death: a fatal combination of obesity, diabetes, and alcoholism. Does Tycho Brahe have a wax nose? In the […]

What is energy carried by electromagnetic waves called? Electromagnetic waves are waves that consist of vibrating electric and magnetic fields. They transfer energy through matter or across space. The transfer of energy by electromagnetic waves is called electromagnetic radiation. How is energy stored in a coil? The energy stored in a magnetic field is equal […]

Which of the following is a technique used to image the relative position of products? Perceptual mapping is a diagrammatic technique used by marketers in an attempt to visually display the perceptions of customers or potential customers. Typically the position of a product, product line, brand, or company is displayed relative to their competition. What […]

Is science absolute or relative? Scientific knowledge by itself is relative; but science can not be satisfied with its relative status, therefore it aspires to absolute, universal, to overcome its relative nature. This aspiration is expressed in extrapolation. Are theories always true? A theory will always remain a theory; a law will always remain a […]
