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?
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 […]
What is energy carried by electromagnetic waves called?
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?
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?
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 […]
What is max current?
What is max current? Ampacity is defined as the maximum current, in amperes, that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Also described as current-carrying capacity. Electric current flowing through them causes voltage drop and power dissipation, which heats conductors. How do you find the maximum and […]
What is the formula for aluminum oxide and why?
What is the formula for aluminum oxide and why? Aluminum oxide has a chemical formula Al2O3. It is amphoteric in nature, and is used in various chemical, industrial and commercial applications. How do you activate aluminum oxide? The preparation method comprises the following steps: (1) dissolving and hydrolyzing solid sodium tetrachloroaluminate by using an ethanol […]

The Dateline Is Not Straight The dateline runs from the North Pole to the South Pole and marks the divide between the Western and Eastern Hemisphere. It is not straight but zigzags to […]
What kind of mixture is salt solution and seawater?
What kind of mixture is salt solution and seawater? The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample. Often it is easy to confuse a homogeneous mixture with a pure substance because they are both uniform. The difference is that the composition of the […]
What does the body use first for energy?
What does the body use first for energy? Carbohydrates are used for energy (glucose). Fats are used for energy after they are broken into fatty acids. Protein can also be used for energy, but the first job is to help with making hormones, muscle, and other proteins. Broken down into glucose, used to supply energy […]
