Is a patellar tendon tear worse than ACL? Aaron Rodgers hurt his “funny bone” and it initially looked worse than it was. The injury is neither funny (quite painful) nor is it a bone (ulnar nerve). What vitamins are good for ligament repair? Vitamin C – also known as ascorbic acid, is a key vitamin […]

What is critical temperature formula? Solution: TC = 647 K, PC = 22.09 Mpa = 22.09 × 103 kPa, VC = 0.0566 dm3 mol-1. Therefore, Van der Waals constant, b = VC/3 = (0.0566 dm3 mol-1)/3 = 0.0189 dm3 mol-1. From the critical constants formula of real gas, a = 3 PC VC2 = 3 […]

What kind of energy does engine produce? Q: The internal combustion engine converts thermal energy to another form of energy. Which form of energy is it? A: The engine converts thermal energy to kinetic energy, or the energy of a moving object—in this case, the moving piston. Are older cars safer? It’s a fact – […]

Can radio waves penetrate skin? For example, microwave frequencies below 3,000 megahertz can penetrate the outer layers of the skin, be absorbed in the underlying tissues, and result in all of the known biological effects of heating, including burns, cataracts, and possibly death. What is a current wave? Currents Tutorial Winds that blow along the […]

What are the five strategic ordering of main points? 5 Types of Main Points. Chronological Order – follow a time pattern or demonstrate how to do something. Spatial Order – following a directional pattern. ( Causal Order – to show a cause effect relationship. Problem-Solution – Two main points…1)first shows the existence and seriousness of […]

What is the safest medical imaging? Ultrasound. Ultrasound is a typically non-invasive and safe form of medical imaging that has a wide range of applications (NPS MedicineWise 2019). Ultrasound uses sound waves rather than ionising radiation. Is a radiologist a doctor? Radiologists are medical doctors that specialize in diagnosing and treating injuries and diseases using […]

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 […]

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 […]
