What are the causes and effects of eutrophication?
What are the causes and effects of eutrophication? “Eutrophication is an enrichment of water by nutrient salts that causes structural changes to the ecosystem such as: increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality and other effects that reduce and preclude use”. What can humans do to […]
What are the three fundamental particles?
What are the three fundamental particles? All three types of fundamental particles—leptons, quarks, and bosons—are described below. The following Figure below shows the variety of particles of each type. How many types of fundamental particles are there? two types What are the fundamental particles in the universe? Particles currently thought to be elementary include the […]
What force prevents an object from moving when pulled?
What force prevents an object from moving when pulled? Friction Does a heavier object move faster? The force of gravity is the weight of the body. Hence an object with greater mass feels greater force than the other one. So even if the slope is same for both objects, a massive object moves faster through […]

What elements have the smallest atomic radius?
What elements have the smallest atomic radius? Explanation: Helium has the smallest atomic radius. Which element has the largest atomic radius K or Na? As an example, potassium (K) has a larger average atomic radius (220 pm)than sodium (Na) does (180 pm). The potassium atom has an extra electron shell compared to the sodium atom, […]
Can you rotate your body in mid air?
Can you rotate your body in mid air? One cannot change one’s angular momentum in mid-air, other than by interaction with the air. A sky-diver, falling through the air after the first few seconds, is falling at “terminal velocity”. Can you rotate in the air? Jump into the air, you can turn your body. Physicists […]
