In space, the following gas laws apply: Avogadro’s law states that the total number of atoms/molecules of a gas (i.e. the amount of gaseous... View Article
If we know the direction of the induced magnetic field then we can easily find the direction of the induced current. By Lenz law, we know that... View Article
A capacitor, when connected to a battery, conducts for awhile but short while after that it acts as an open circuit. If an uncharged capacitor C... View Article
Power cycles are cycles which convert the input heat into mechanical work output. In Heat pump cycles, heat is transferred from low to high... View Article
Loudness is the property of sound that describes how loud or soft a sound seems to a listener. The intensity of the sound waves determines the... View Article
The De Broglie wavelength doesn’t directly depend on the charge; however, it depends on the momentum. Therefore, if an electric field accelerates... View Article
Yes, a body can be in equilibrium if it is in motion. We call this type of equilibrium as a dynamic equilibrium. We know that a body is said to... View Article
The carbon rod in a dry cell doesn’t take part in the electrochemical reactions that occur in a cell to produce an electric current. However, the... View Article
In case the electric field is not normal to the surface of the conductor, then it will have a component that is tangential to the surface which... View Article
