This is an application to Faraday's and Lenz' laws of electromagnetic induction. So as the magnet moves into the coil, the magnetic field from the magnet moves through the coil, therefore there is a chang...
The derivative of distance with respect to time is velocity.
To understand why the water evaporates, we need to know what we mean when we say something has a certain temperature. Temperature is proportional to the average kinetic energy of the microscopic molecules...
In a question like this, you will be given that the molar gas constant is R = 8.31JK-1mol-1. However, committing this to memory will be helpful. We should use the ideal gas law: PV =...
State Coulomb's law:F=(1/4πE0 )(qQ/d2)Since the distance separating the charges is twice the radius of the orbit relabel d to 2r and the charges are equal and opposite:F= -(1/16π...
