How much heat is required to raise the temperature? To calculate the energy required to raise the temperature of any given substance, here’s what you require: The mass of the material, m. The temperature change that occurs, ΔT. The specific heat capacity of the material, c (which you can look up). Here is a source […]

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 […]

Is black body always black? No radiation passes through it and none is reflected, yet in classical physics, it can theoretically radiate any possible wavelength of energy. Despite the name, black bodies are not actually black as they radiate energy as well. What is a black body Class 11? A black body is an idealization […]

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 […]

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 […]

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 […]

How does Mildred die? Montag finds Mildred passed out, having overdosed on thirty plus sleeping pills. Her stomach is pumped and her blood re-circulated. The next morning she doesn’t remember any of it. Why can’t Montag run away? Physically, Montag is unable to run as fast as he would like because of his confrontation with […]

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 […]

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 […]
