What is the charge acquired by a body when 1 million electrons are transferred to it? what is the charge acquired by a body when 1 million electrons are transferred to it ? The object acquires a charge of 1.602×10^-13 coulombs. What is the minimum charge acquired by a body? A body can be charged […]

Why is the surface perfection of glass fibers so important? The surface perfection of glass fibers is important because surface flaws or cracks will act as points of stress concentration, which will dramatically reduce the tensile strength of the material. Care must be taken not to rub or abrade the surface after the fibers are […]

Does the speed at which you move the magnet inside of the coils have any effect on voltage? Yes, the speed at which you rub the magnet has an effect on voltage. When you rub it faster the light and the volts increase. How do you calculate induced current in a coil? The magnitude of […]

What is F MA Math? The famous formula is: F = ma. “Newton’s Second Law of Motion” (F is force, m is mass and a is acceleration) Do you need calculus for F MA? F=ma does not require any Calculus background. It is a test designed to challenge your understanding and intuitive on the most […]

Why is public transport safer than cars? Crash Risk Crash risk refers to property damages, injuries and deaths caused by vehicle crashes. Public transit has relative low crash rates per unit of travel, as indicated in Table 3 and Figure 1. Public transit passengers have far lower traffic casualty rates than automobile occupants. Should buses […]

Is entropy the same as chaos? Entropy is the measure of disorder in a system. Chaos is another word for disorder. Entropy is a measure of how likely the system will be in a certain macrostate, because of how many microstates correspond to it. It is also a measure of how much the energy is […]

Do not stand too close to moving? “ When a train moves, there is a matter wave attached to it. Waves move from positive to negative. Outside of train is positive and inside is negative. So, the train may pull us towards it if we stand very close to it.” Why do we get pulled […]

When we push a wall no work is done? In this case the wall does not displace from its position even though the force is applied and since displacement is zero work done is said to be zero. Is pushing against a wall work? Note that forces without motion do no work. For example, if […]

What is the difference between closed head injury and concussion? A concussion is a type of closed head injury, which is often referred to as a traumatic brain injury or TBI. The symptoms of concussion include headache, dizziness, sleep disturbances, visual changes, difficulty with balance, fatigue and memory problems. TBI encompasses many more brain injuries […]
