How do you calculate angular velocity? ω = v/r, where ω is the Greek letter omega. Angular velocity units are radians per second; you can also treat this unit as “reciprocal seconds,” because v/r yields m/s divided by m, or s-1, meaning that radians are technically a unitless quantity. What is the angular displacement of […]
Why do we have two eyeballs?
Why do we have two eyeballs? Humans have two eyes, but we only see one image. We use our eyes in synergy (together) to gather information about our surroundings. They show each eye a slightly different image. The two images show the objects as seen from slightly different angles, as would be when you saw […]
Is Sun going to rise from west?
Is Sun going to rise from west? And this weird phenomena of the opposite movement is called “Retrograde Motion” Most scientist state that all the planets will go through the same once at least and our planet Earth is one of them. Planet Earth will move in the opposite direction some day and the sun […]

What is the formula for work in science?
Do facts change over time?
Do facts change over time? Facts are simple observations of the world, and they do not change over time. Theories are hypotheses about what these facts mean, or how they should be understood, and they change over time. But, they may still change over time. This view supposes that the process of observation is completely […]
What is LHC experiment?
What is LHC experiment? LHC experiments Eight experiments at the Large Hadron Collider (LHC) use detectors to analyse the myriad of particles produced by collisions in the accelerator. These experiments are run by collaborations of scientists from institutes all over the world. Each experiment is distinct, and characterised by its detectors. What is a beauty […]
Is it possible for polluted water to be transported to another country?
Is it possible for polluted water to be transported to another country? Transboundary pollution is the pollution that originates in one country but is able to cause damage in another country’s environment, by crossing borders through pathways like water or air. Pollution can be transported across hundreds and even thousands of kilometers. This is why […]
What happens to current if voltage stays the same and resistance increases?
What happens to current if voltage stays the same and resistance increases? If the voltage stays the same, but resistance goes up, what happens to the amperage? Assuming a constant voltage, the current is inversely proportional to the resistance. To answer the question, if the resistance goes up, the current (amperage) goes down. What happens […]
What is the strongest argument for the death penalty?
What is the strongest argument for the death penalty? The argument most often cited in support of capital punishment is that the threat of execution influences criminal behavior more effectively than imprisonment does. As plausible as this claim may sound, in actuality the death penalty fails as a deterrent for several reasons. What is the […]
