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 […]
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 […]
Are Relays AC or DC?
Are Relays AC or DC? A Dc relay coil has resistance that limits the dc current. An AC coil relies on its impedance for governing the current. An AC relay will remain contact closed due to mechanical inertia and a little mechanical hysteresis and, the fact that an alternating north and south pole both attract […]
Is Apple a producer?
Is Apple a producer? As the book describes, an intermediary “is the link in the supply chain that links the producer or other intermediaries to the end consumer.” So in this case Apple is the producer, Apple Pay is the intermediary (or middleman), and the users of Apple Pay are the consumers. What makes mold […]

The Uphill Water Fountain – a fountain that flows upwards. One-sided bulletproof glass – protect and shoot at the same time. Starlite – The miracle material […]
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 formula for ionization energy? Calculate the ionization energy, in units of electron volts, for a one-electron atom by squaring Z and then multiplying […]
What is the chemical property of a metal statue?
What is the chemical property of a metal statue? Density is one property that is the same for the water in both beakers, even though volume is different. The ability to tarnish is an example of a chemical property of a metal statue. What statement describes a chemical property of an object? A chemical property […]
