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 […]
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 […]
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 […]

How can we use electromagnet in everyday life? Electromagnets are found in doorbells, hard drives, speakers, MagLev trains, anti-shoplifting systems, MRI machines, microphones, home security systems, VCRs, tape decks, motors, and many other everyday objects. What are 4 properties of magnets? They are: Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel. […]
How might environmental manipulation of crops have unexpected consequences?
How might environmental manipulation of crops have unexpected consequences? Explanation: Manipulation of a crop has several unanticipated consequences; such that the new crop may require more water, it may harm the environment and its yield may be limited. More water might be required for the crops to grow and the yield declined. Which of the […]
