What is a principle of moment? The Principle of Moments states that when a body is balanced, the total clockwise moment about a point equals the total anticlockwise moment about the same point. How do you find SFD and BMD? Shear Force & Bending Moment Diagram of Simply Supported Beam Draw shear force and bending […]
What element in the second period has the largest?
What element in the second period has the largest? Lithium Which group has the highest electronegativity? fluorine What 3 elements have the highest electronegativity? Thus, fluorine is the most electronegative element, while francium is one of the least electronegative. (Helium, neon, and argon are not listed in the Pauling electronegativity scale, although in the Allred-Rochow […]
Why do we not use geothermal energy?
Why do we not use geothermal energy? One major concern around geothermal energy, as articulated by GreenMatch, is in regards to its extraction — often, the extraction of geothermal energy “leads to a release of greenhouse gases like hydrogen sulfide, carbon dioxide, methane and ammonia.” While this shouldn’t be ignored, it is worth noting that […]

What can you do to get water to return to its liquid state if it has changed to a gas?
What can you do to get water to return to its liquid state if it has changed to a gas? The easy answer is to lower the surrounding temperature. When the temperature drops, energy will be transferred out of your gas atoms into the colder environment. When you reach the temperature of the condensation point, […]

Explanation: If surface has a large number of valleys and hills. Explanation: If ‘θ’ angle between optical flat and surface whose flatness to be measured […]
Why is noise pollution bad for whales?
Why is noise pollution bad for whales? Recent studies suggest that noise pollution can harm whales directly by damaging their hearing, and in extreme cases, causing internal bleeding and death. More commonly, it appears that excessive or prolonged noise can cause behavioral changes that interfere with the health and survival of the animals. How we […]
Can a magnet repel ferromagnetic material?
Can a magnet repel ferromagnetic material? Magnets are always attracted to ferromagnetic substances like iron, cobalt, nickel and the alloys containing them (example: steel). Ferromagnetic materials not only get attracted to magnets, but they can also retain the magnetic properties after the magnet is removed. How do you get a magnet to repel? Every magnet […]
