What is the advantage of resistance? Connection of resistance reduces current and protects the instruments from getting high currents. Resistance also increases battery life as less current is drawn. Also, there are many disadvantages like power is wasted. Resistance carrying electric current generates heat energy, which is used for useful purposes. What are the disadvantages […]

Can fingernails indicate health issues? Did you know your nails can reveal clues to your overall health? A touch of white here, a rosy tinge there, or some rippling or bumps may be a sign of disease in the body. Problems in the liver, lungs, and heart can show up in your nails. What should […]

Are chlorofluorocarbons toxic? Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants. What causes the release of chlorofluorocarbons? The most common emitter of CFCs are refrigerants, particularly those used after […]

What is the inverse of tan 0? Arctan graph x arctan(x) rad ° -1 -π/4 -45° -√3/3 -π/6 -30° 0 0 0° What is inverse tan on a calculator? The arctangent function is the inverse function of y = tan(x). What is the value of tan inverse 1 upon root 3? Evaluate the exponent. The […]

Can automatic cars be fast? It’s easy to see why a lot of people believe that a stick shift helps a car launch off the line more quickly and accelerate better. But thanks to advancements and innovations that have helped automatic transmissions become more efficient, they’ve easily surpassed the reliable old manual in terms of […]

How do you read audiometry results? Frequency is measured horizontally on the top of your hearing test. As the frequencies go from left to right they range from lower to higher. Example: If you read the audiogram from left to right, the final X is all the way at 8,000 hertz – that means this […]

What color light travels fastest? red Which travels faster blue or red light? Because the number of subquantum energy in a red photon is less than that of a blue photon, red photon interactions are less than the blue photon in the medium. So, the red light travels faster than the blue light. How can […]

What is the most important system in the body? One of the most important systems in your body, the nervous system is your body’s control system. It sends, receives, and processes nerve impulses throughout the body. These nerve impulses tell your muscles and organs what to do and how to respond to the environment. What […]

What is the difference between ASME and ASTM? Basically ASTM creates the material specifications and standard test methods to determine compliance. ASME selects those ASTM materials which will perform adequately in boiler or pressure vessel service and accepts them with stated limitations. What does AISI mean in steel? American Iron and Steel Institute What is […]

Can lack of sleep make you psychotic? The finding that sleep deprivation can apparently produce symptoms of acute psychosis in healthy individuals adds to the evidence linking sleep and psychosis. In support, various studies show that prolonged sleep loss is both a precursor and precipitant to psychosis (8, 10–12). What a psychotic break looks like? […]
