What are the 5 stages of writing? The Writing Process STEP 1: PREWRITING. THINK AND DECIDE. Make sure you understand your assignment. STEP 2: RESEARCH (IF NEEDED) SEARCH. List places where you can find information. STEP 3: DRAFTING. WRITE. Put the information you researched into your own words. STEP 4: REVISING. MAKE IT BETTER. STEP […]

Are we evolving right now? Contrary to popular belief, not only are humans still evolving, their evolution since the dawn of agriculture is faster than ever before. For example, while human DNA is on average 98% identical to chimp DNA, the so-called Human Accelerated Region 1 (HAR1), involved in the development of the brain, is […]

What is the equation of reduced mass? The quantity m is called the reduced mass. Equation RM-6 describes the motion of m1 relative to m2; that is, we can consider m2 to be the center of mass (and the coordinate origin) if we substitute the reduced mass m for m1. What is the reduced mass […]

Why is energy released in fusion? In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy. Fusion can involve many different elements in […]

What is the oxidation number of H? +1 What is oxidation number of oxygen in OF2? +2 What is the oxidation number Charge of oxygen *? Oxygen has an oxidation number of −2 in most compounds. The major exception is in peroxides (compounds containing O X 2 X 2 − \ce{O2^2-} OX2X2−), where oxygen has […]

Are hair splinters rare? While hair splinters are rare for some people, those who handle a lot of hair may develop them from time to time. If you notice one, try to remove it as soon as possible to avoid infection. If you’re having trouble reaching the hair, or the area looks inflamed, it’s best […]

Can I use gel polish without UV light? While you will be able to apply gel nail polish without a UV light, the other “processes” of drying are long and will not give the quality results you expect. A UV light is what dries the gel quickly and without fail. It’s impossible to air it […]

What property of the object has a relationship with the displaced volume? The amount of fluid displaced is directly related (via Archimedes’ principle) to its volume. In the case of an object that sinks (is totally submerged), the volume of the object is displaced. In the case of an object that floats, the amount of […]

What is the momentum of the bowling ball? 30 kg m/s Why does a bowler run before the ball is delivered? Answer: The bowler runs before delivering the ball in cricket to acquire kinetic inertia so that he can deliver the ball faster. The bowler brings himself in the state of motion by running so […]

What is the change of state of matter from liquid to gas? (b) The process of change of a substance from a liquid state to its gaseous state at a particular temperature is called boiling and the temperature at which it happens is called the boiling point. What are some examples of gas solutions? 13.1: […]
