What are the two types of reflection? The reflection of light can be roughly categorized into two types of reflection. Specular reflection is defined as light reflected from a smooth surface at a definite angle, whereas diffuse reflection is produced by rough surfaces that tend to reflect light in all directions (as illustrated in Figure […]

What are 2 types of kinetic friction? In general, the friction is of the following two types: (1) Static friction. It is the friction, experienced by a body, when at rest. (2) Dynamic friction. It is the friction, experienced by a body, when in motion. (a) Sliding friction. (b) Rolling friction. (c) Pivot friction. 14.7. […]

What is the most important part of the electromagnetic spectrum? Infrared (IR) radiation – also referred to as thermal radiation – is the portion of the electromagnetic spectrum lying between visible light and microwaves. The most important natural source of infrared radiation is the sun. What is the order of increasing wavelength? The electromagnetic spectrum […]

What do we use carbon 13 for? Such compounds are safe because they are non-radioactive. In addition, 13C is used to quantify proteins (quantitative proteomics). One important application is in “Stable isotope labeling with amino acids in cell culture” (SILAC). C-enriched compounds are used in medical diagnostic tests such as the urea breath test. Why […]

What does Saturn stand for? “Saturn is about maturity, responsibility, discipline, and stewardship,” says Jennifer Freed, PhD, psychological astrologer and author of Use Your Planets Wisely. “Look at each sign and what it means to be mature using its archetypal energy.” What does Saturn mean spiritually? Saturn is associated with the higher chakras and specifically […]

How deep can a magnetometer go? The corresonding sources can be from several hundred metres to 1000 metres or more, depending, as indicated before, on the “size” of the buried object or geologic horizon. Breiner, S., 1973. Applications Manual for Portable Magnetometers. How can a magnetometer be used to determine North? If the device is […]

What is the sweetest sugar? Fructose Can something sweet without sugar? Absolutely not, assuming that you want to enjoy naturally-occurring sweet food items and still stay healthy in the long run. This can seriously mess up your sugar receptors through overstimulation, and can consequently make naturally-occurring sweet foods (like fruits) taste a lot less sweet […]

How do you convert SI units? 1 Answer. Multiply or divide by powers of 10. SI units are easy to convert because you multiply or divide by 10 – sometimes more than once. Think of a staircase – every time you step up a stair, you divide by 10; every time you step down a […]

What happens when you bring a magnet close to some paper clips? If you bring a bar magnet close to pile of paper clips, the paper clips will become temporarily magnetized. As a result, the paper clips will stick to the magnet. They will also stick to each other. Once the magnet is removed the […]

How many properties do ionic compounds have? Properties of Ionic Compounds Ionic Compounds have high boiling and melting points as they’re very strong and require a lot of energy to break. The electrostatic forces of attraction between oppositely charged ions lead to the formation of ions. Ionic compounds form crystals. Is sugar a covalent or […]
