What is the relation between current and intensity? This current is the number of electrons being emitted per second. That is directly proportional to the intensity of the light. So greater intensity means more photons striking the surface and hence an increase in the emitted electrons. The frequency of the light tells is about the […]
Can the scientific method be cyclic?
Can the scientific method be cyclic? How does it work? The scientific method involves a cyclic process of observation, hypothesis and experimentation. Why is the scientific method not really linear? In contrast to the linear steps of the simplified scientific method, this process is non-linear: The process of science is iterative. Science circles back on […]
What is crust explain?
What is crust explain? “Crust” describes the outermost shell of a terrestrial planet. Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. […]
What is ionized helium?
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 much does it cost to replace seatbelts?
How much does it cost to replace seatbelts? The cost of a replacement seat belt varies depending on your vehicle’s specific year, make, and model. OE replacement parts will generally cost you anywhere between $20 to $85. Replacement seat belt assemblies are usually sold individually. Can seat belts be repaired or are they to be […]
Can a person live without bone marrow?
Can a person live without bone marrow? It is the blood cell ‘factory’. Healthy bone marrow releases blood cells into the bloodstream when they are mature and when required. Without bone marrow, our bodies could not produce the white cells we need to fight infection, the red blood cells we need to carry oxygen, and […]
What are the important topics in electric charges and fields?
What are the important topics in electric charges and fields? Important Topics: Coulomb’s Law. Forces between multiple charges electric field due to system of charges. 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?
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 […]
Why is area and perimeter important?
Why is area and perimeter important? Perimeter and Area. Perimeter and area are two important and fundamental mathematical topics. They help you to quantify physical space and also provide a foundation for more advanced mathematics found in algebra, trigonometry, and calculus. What is the importance of perimeter in real life? In everyday life area and […]
What is a potential divider used for?
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 […]
