What is the difference between a pelican and a puffin crossing? Puffin. Crossings differ from Pelican crossings, as they do not have a flashing green man/flashing amber signal. This layout encourages pedestrians waiting at the crossing to look at the approaching traffic at the same time as looking at the red man/green man signal. Who […]
In what direction is the net force exerted on the moon?
In what direction is the net force exerted on the moon? We know from Newton’s second law of motion that an object experiencing a net force undergoes acceleration. In the case of the moon orbiting the Earth (or any object orbiting another object to which it is attracted by some force), the net force on […]

What type of research is a descriptive study?
What type of research is a descriptive study? Descriptive research is a type of research that describes a population, situation, or phenomenon that is being studied. It focuses on answering the how, what, when, and where questions If a research problem, rather than the why. What type of descriptive research study measures a population at […]

Does anything have 100 efficiency?
Does anything have 100 efficiency? A system can never be 100% efficient. The reason behind this is because of heat and sound energy are lost in some amount in every system. No matter they are waste or not. So a system doesn’t exist, with 100% efficiency. Is human body energy efficient? Alas, our bodies are […]
How do I make my bestie miss me?

What is the process of an electromagnet?
What is the process of an electromagnet? An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil. […]
What is the formula for acceleration using distance and time?
What is the formula for acceleration using distance and time? Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes […]
