Is upthrust a frictional force?
Is upthrust a frictional force? Friction is a force caused by two things rubbing together. Air resistance and water resistance are kinds of friction. Upwards forces from water or air are called upthrust. Things float in water because of upthrust. What’s the difference between upthrust and drag force? The force of upthrust equals the weight […]
What is load force?
What is load force? Force is a measure of the interaction between bodies. Force is known as a vector quantity, as it has both direction and magnitude. Load. Load is a term frequently used in engineering to mean the force exerted on a surface or body. What is the formula of load? Multiply the mass […]
What is the importance of Arrhenius equation?
What is the importance of Arrhenius equation? The Arrhenius equation can be used to determine the effect of a change of temperature on the rate constant, and consequently on the rate of the reaction. If the rate constant doubles, for example, so does the rate of the reaction. What are the 6 factors that affect […]
What do spores release?
What do spores release? Spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes. Where can fungi spores be found? Fungal spores […]
What are the 5 basic components an ecosystem needs?
What are the 5 basic components an ecosystem needs? In order to survive, ecosystems need five basic components: energy, mineral nutrients, water, oxygen, and living organisms. What are the two main components of the ecosystem? Every ecosystem has two components, namely, biotic components and abiotic components. Biotic components refer to all living organisms in an […]
What is the highest ionization energy?
What is the highest ionization energy? helium What has the greatest influence on the first ionization energy? Size of nuclear charge. Distance of outer electrons from the nucleus. Shielding. What is the formula for ionization energy? Calculate the ionization energy, in units of electron volts, for a one-electron atom by squaring Z and then multiplying […]
Why are economic models not realistic?
Why are economic models not realistic? Most economic models rest on a number of assumptions that are not entirely realistic. For example, agents are often assumed to have perfect information, and markets are often assumed to clear without friction. Or, the model may omit issues that are important to the question being considered, such as […]
