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. […]

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 […]

At what angle a player should throw a javelin to achieve maximum range? 45 degrees At what angle do you launch a ball to achieve longest range? The sine function reaches its largest output value, 1, with an input angle of 90 degrees, so we can see that for the longest-range punts 2θ = 90 […]

What is Heisenberg Uncertainty Principle explain? Heisenberg’s uncertainty principle is a key principle in quantum mechanics. Very roughly, it states that if we know everything about where a particle is located (the uncertainty of position is small), we know nothing about its momentum (the uncertainty of momentum is large), and vice versa. What is the […]

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, […]

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 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 […]

How long does a passive RFID tag last? about 20 years What is inside a passive RFID tags? In PASSIVE RFID Tags we have generally two main components. One is ANTENNA COIL and another is MICROCHIP. As you can see in the above image, there is no BATTERY or any other ACTIVE POWER here. How […]

When a horse pulls a wagon the force that causes the horse to move forward is the force? As per Newton’s third law of motion, when a horse pulls a wagon, the force that causes the horse to move forward is the force the ground exerts on it. What is the effort needed to lift […]

What are dependent and independent variables in research? In research, variables are any characteristics that can take on different values, such as height, age, species, or exam score. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes […]
