Does acceleration due to gravity depend on mass? The acceleration due to gravity does not depend on the mass of the object falling, but the force it feels, and thus the object’s weight, does. Why does mass resist acceleration? The more mass an object has the more weight it will have. Weight is caused by […]
Can we charge an insulator?
Can we charge an insulator? Charge cannot flow along or through an insulator, so its electric forces remain for long periods of time. (Charge will dissipate from an insulator, given enough time.) Do conductors attract insulators? If the insulator started with positive charge on it, that means electrons are missing inside of it. The electrons […]

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 […]
Who invented inches?
Who invented inches? The old English ynce was defined by King David I of Scotland about 1150 as the breadth of a man’s thumb at the base of the nail. To help maintain consistency of the unit, the measure was usually achieved by adding the thumb breadth of three men—one small, one medium, and one […]
Is rural living safe?
Is rural living safe? Compared to cities and suburban areas, rural locations are the most dangerous places to live. A study found that “your risk of death is actually about 22 percent higher in the most rural counties in America than in the most urban ones.” Death rates in the exurbs are higher for a […]

Can you drive in freezing rain?
Can you drive in freezing rain? Don’t drive, if you don’t have to. If you are aware of freezing rain conditions, stay home. Even with the reduction of speed, slick conditions like freezing rain just means that you will slide slower across the ice-ridden roads. Is driving with sleet dangerous? One of the reasons it […]
When an electric current operates a buzzer makes a sound?
When an electric current operates a buzzer makes a sound? Explanation: When a buzzer is attached to a certain circuit and we press the key then the circuit gets complete. As a result, the current will start to flow from the batter or cell and moves towards the buzzer. Thus, buzzer produces sound due to […]
