Which fabric is the best insulator? Wool fibers are woven tightly together, and are much thicker than other materials, such as cotton. They don’t allow much heat to escape, which means they are great insulators. Fabrics like cotton and lace are breathable fabrics, meaning they allow a great deal of heat to escape. Is felt […]

What causes acceleration problems in a car? What Causes Acceleration Problems? Hiccups in air and fuel delivery and sensor issues are the main causes of poor acceleration. However, mechanical issues can also be the cause of low power. What makes a car accelerate faster? Basically, the faster the crankshaft spins with the same amount of […]

What is the advantage of CCD scanner? In general, CIS allows the construction of smaller sizes as well as lower power consumption, while CCD technology allows a higher depth of field, higher speed and signal noise ratio and better colour accuracy – so higher quality and productivity. What cameras have CCD sensors? CCD Still Has […]

Does the Mirror show the real you? In short, what you see in the mirror is nothing but a reflection and that may just not be how people see you in real life. In real life, the picture may be completely different. All you have to do is stare at a selfie camera, flip and […]

What is 9.31 g the same mass as? 0.00931 kg What is the density of a medication sample if 3.00 mL has a mass of 3.85 g? ρstuff=3.85⋅g3.00⋅mL=1.28⋅g⋅mL−1 … Is g mL a unit of density? The mass of water is expressed in grams (g) or kilograms (kg), and the volume is measured in liters […]

How can I charge my phone without a charger? All of these methods require either a charging cable that’s compatible with your iPhone or Android device or a wireless charging pad. Use a USB Port to Charge Your Phone. Charge Your Phone With a Battery Pack. Hand-Crank Chargers for Emergency Phone Charges. Use an Eco-Friendly […]

What is the force that opposes weight and allows an airplane to fly? Lift When a plane is flying at a constant speed which two forces must be balanced? All Four Forces Act on an Airplane When an airplane is flying straight and level at a constant speed, the lift it produces balances its weight, […]

How a barrel of oil is used? For many, a barrel of oil is almost synonymous with its most prominent product, gasoline. While almost 40% of a barrel of oil is used to produce gasoline, the rest is used to produce a host of products including jet fuel and plastics and many industrial chemicals. What […]

What is Hypsochromic shift example? Hypsochromic shift is a phenomenon seen in molecular spectra, not atomic spectra – it is thus more common to speak of the movement of the peaks in the spectrum rather than lines. For example, β-acylpyrrole will show a hypsochromic shift of 30-40 nm in comparison with α-acylpyrroles. Why does red […]

What happens if index of refraction is less than 1? Refractive indices less than 1 can occur and if the phase velocity of the light in the medium is faster than the speed of light. Negative refractive indices can occur if both the permittivity and permeability of the material are both negative at the same […]
