Which Colour is the coldest star? red What is the coldest thing in earth? A chunk of copper became the coldest cubic meter (35.3 cubic feet) on Earth when researchers chilled it to 6 millikelvins, or six-thousandths of a degree above absolute zero (0 Kelvin). This is the closest a substance of this mass and […]
What is the enlarged muscular sac like organ present in our body?
What is the enlarged muscular sac like organ present in our body? Gallbladder: This sac-like organ stores bile produced by the liver and then releases it as necessary. Where is poop stored in our body? A stool is stored in the sigmoid colon until a “mass movement” empties it into the rectum once or twice […]
How do anaerobic bacteria get energy?
How do anaerobic bacteria get energy? Fermentation. Fermentative anaerobic organisms mostly use the lactic acid fermentation pathway: C6H12O6 + 2 ADP + 2 phosphate → 2 lactic acid + 2 ATP. The energy released in this equation is approximately 150 kJ per mol, which is conserved in regenerating two ATP from ADP per glucose. What […]
Why is vibration a serious health issue?
Why is vibration a serious health issue? Vibration can cause changes in tendons, muscles, bones and joints, and can affect the nervous system. Collectively, these effects are known as Hand-Arm Vibration Syndrome (HAVS). Workers affected by HAVS commonly report: attacks of whitening (blanching) of one or more fingers when exposed to cold. Can anxiety make […]
Why face centered cubic exist?
How do you find the angle of depression?
How can we make solar cells more efficient?
How can we make solar cells more efficient? One cost-effective way to improve efficiency is to build a tandem device made of silicon and another inexpensive photovoltaic material, he said. “Making low-cost tandems is very desirable,” McGehee said. “You simply put one solar cell on top of the other, and you get more efficiency than […]
Will water ever disappear from Earth?
Will water ever disappear from Earth? Earth never gets water added to it–nor does water disappear from the earth. Water is constantly recycled in a process known as the hydrologic or water cycle. Fresh water is more scarce than you might think. 97% of all the water on the earth is in the oceans, and […]

What would be the electronic configuration of a positively charged sodium ion Na+?
What would be the electronic configuration of a positively charged sodium ion Na+? The positively charged sodium ion will have an electron less than its atomic number, we will remove an electron from the last valence shell of sodium that is 3s1. So the sodium ion will have ten electrons. The electronic configuration of Na+ […]
