Electric dipole’s electric field on axial and equatorial point. Electric dipole in external electric field. Gauss’s law applications. What are the most important topics in physics? NEET 2021 Class 12th […]

What were the major conflicts of the Cold War? The Korean War, Vietnam War, and a number of other armed conflicts, during which both sides either funded one side of the war or fought directly against a communist or capitalist force, are all considered Cold War proxies. Why the US was responsible for the Cold […]

What is a potential divider used for? A potential divider is a simple circuit that uses resisters(or thermistors / LDR’s) to supply a variable potential difference. They can be used as audio volume controls, to control the temperature in a freezer or monitor changes in light in a room. Why do we need voltage? Electrical […]

What is ionized helium? Singly ionized helium is an atom that has lost one of its electrons. We must expect its remaining electron to act like a hydrogen electron. There is only one difference between a hydrogen atom and a singly ionized helium atom; number of protons in the nucleus, so the nuclear charge. What […]

How do rocks and soil move downslope? Mass wasting – is movement in which bed rock, rock debris, or soil moves downslope in bulk, or as a mass, because of the pull of gravity. Landslides is a general term for the slow-to-very rapid descent of rock or soil. Flow – The debris is moving downslope […]

When atoms are bombarded with alpha particles only a few in million suffer deflection others pass out Undeflected This is because? When atoms are bombarded with alpha particles, only a few in millon suffer deflection, other pass out undeflected. This is because. The nucleus occupies much smaller volume compared to the volume of the atom. […]

Does the atomic radius increase from left to right? Atomic radius is determined as the distance between the nuclei of two identical atoms bonded together. The atomic radius of atoms generally decreases from left to right across a period. The atomic radius of atoms generally increases from top to bottom within a group. What is […]

How do you use the word use and used? Used to refers to something familiar or routine, as in “I’m used to getting up early for work,” or to say that something repeatedly happened in the past like “we used to go out more.” Use to typically occurs with did; “did you use to work […]

What is the Sun an example? The sun is the star that is the central object in the solar system. It is made up of 92% hydrogen, almost 8% helium and the rest is assorted elements. An example of sun is what rises in the east and sets in the west each day. The radiant […]

What two factors can make an object stable? The stability of an object is dependent on two factors: The base width of the object. The center of gravity. What are structures for Grade 3? A structure is a solid that has a shape, size, and purpose. It holds a load. Example: A tennis shoe is […]
