What is the application of third law of thermodynamics? The third law of thermodynamics states that the entropy of a perfect crystal at a temperature of zero Kelvin (absolute zero) is equal to zero. Entropy, denoted by ‘S’, is a measure of the disorder/randomness in a closed system. All the atoms and molecules in the […]
What are the properties of an acid and a base?
What are the properties of an acid and a base? Chemistry Property Acid Base Taste Sour (vinegar) Bitter (baking soda) Smell Frequently burns nose Usually no smell (except NH3!) Texture Sticky Slippery Reactivity Frequently react with metals to form H2 React with many oils and fats How is an acid and a base different? A […]
How do I check my Etabs time period?
How do I check my Etabs time period? The time period (the one-story model of the structure is below) calculated manually by using the equation in IS 1893: 2016 is 0.170963 and that given by Etabs 2017 is 0.171 (highlighted in the picture below). How do you calculate time period of vibration? As the frequency […]
Is a primary wave transverse?
Is a primary wave transverse? When seismic waves are first created, they travel outwards in all direction from their source. Body waves travel through the interior of the earth, and have two main types: P-Waves (Primary waves) are Longitudinal Waves. S-Waves (Secondary waves) are Transverse Waves. Do P or S waves cause more damage? S […]
Does positive and negative matter with lights?
Will toddlers grow taller if they drink more milk hypothesis?
Will toddlers grow taller if they drink more milk hypothesis? As best as the current science can answer it, no, milk doesn’t make you grow taller, simply because, well, nothing can make you grow taller. But milk can be a useful tool to help kids grow to their potential height. What is a formalized hypothesis? […]
Where does the dark go when you turn on the light?
What is the best anti-vibration material?
What is the best anti-vibration material? Rubber Where are vibration isolators used? Vibration Isolation Pad Mounts Pads or sheets constructed of flexible materials such as elastomers, rubber, cork, dense foam and laminate materials are often used under heavy machinery, under common household items, in vehicles and other applications to reduce noise and vibration transmission. What […]
What is wet lab skills?
What is wet lab skills? A wet lab is one where drugs, chemicals, and other types of biological matter can be analyzed and tested by using various liquids. On the other hand, a dry lab environment focuses more on applied or computational mathematical analyses via the creation of computer-generated models or simulations. What are some […]
Should you land on your toes when running?
Should you land on your toes when running? Landing on the toes distributes the impact of running completely differently than heel striking. Instead of absorbing the impact through knees, toe strikers do so through their ankles and Achilles tendons. Is it better to run on toes or heels? Others claim, that easier form doesn’t mean […]
