How much force is required to produce an acceleration? Answer. The SI unit of force is Newton or N. So, the force needed to produce an acceleration of 2 m/s in a body of mass 3 kg is 6 N. What force is required to produce an acceleration? Weight and the Gravitational Force. When an […]
Is it always a good idea to update your operating system?
Is it always a good idea to update your operating system? It would be a good idea to consider upgrading to the newest version before your current system reaches end of life, so that you can ensure your information is protected. With enhanced security, better support, and compatibility with new programs, updating just makes sense. […]
Is flow rate a vector?
Is flow rate a vector? 1 Velocity, speed, flow rate, and acceleration. Velocity indicates the distance and the direction of a motion, and is called a vector quantity. To define a vector quantity, both magnitude and direction are needed. What is the unit of flow rate? In S.I. units (International System of Units), volume flow […]
What is a watershed explain?
What is a watershed explain? A watershed is an area of land that drains all the streams and rainfall to a common outlet such as the outflow of a reservoir, mouth of a bay, or any point along a stream channel. Why do we need watersheds? Watersheds are important because the surface water features and […]
What happens to equilibrium when a strong acid is added?
What happens to equilibrium when a strong acid is added? If hydrochloric acid was added to the equilibrium mixture, both hydrogen ions (H +) and chloride ions (Cl -) are being added. Hydrogen ions are on the right hand side of the equilibrium, therefore the equilibrium will shift to the left hand side to compensate, […]
Are we due for another Ice Age?
Are we due for another Ice Age? Researchers used data on Earth’s orbit to find the historical warm interglacial period that looks most like the current one and from this have predicted that the next ice age would usually begin within 1,500 years. What is the biggest problem with climate change? Climate change is already […]
Why was Arctic sea ice so low in 2012?
Why was Arctic sea ice so low in 2012? It’s clear that Arctic sea ice is declining over time, although there are ups and downs each year. And scientists say the melt has been driven by both global warming and other pollutants that humans have put into the atmosphere. What was the sea ice minimum […]

What do prokaryotes and eukaryotes have in common?
What do prokaryotes and eukaryotes have in common? Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. Ribosomes are the non-membrane bound organelles where proteins are made, a process called protein synthesis. Do prokaryotic and eukaryotic cells have Golgi bodies? Eukaryotic cells contain a membrane-bound […]
