Gold is classified as a heavy metal despite its softness and malleability. Each atom of gold is heavy on its own. Gold has a mass density 19.3 g/cc.... View Article
Gold is much heavier than lead. The mass density of gold is 19.3 g/cc and the mass density of lead is 11.4 g/cc. (1 g/cc = 1 grams per cubic... View Article
The boiling point of the hydrocarbons increases with the increase in the carbon atoms and the maximum molecular weight. Dodecane is a liquid... View Article
All the hydrocarbons are flammable. LPG is made from hydrocarbons. The main hydrocarbons of LPG are propane and butane. LPG burns readily in air,... View Article
Electric field is created when there is a difference of voltage. The Electric fields are produced by unit charge or by varying magnetic fields.... View Article
The portion of the frequency spectrum that has most of the signal energy is called the essential bandwidth. Fractional bandwidth is calculated by... View Article
The three forms of Ohm’s law relating voltage, current and resistance is that For constant current flow, the resistor is given by the ratio of... View Article
Resistance is the opposition to the flow of current. Ohm’s law gives the relationship between current, voltage and resistance. From Ohm’s law,... View Article
Two sources are said to be coherent if the waves have the same frequency and a constant phase difference. The coherent sources are produced in... View Article
No, heat causes irreversible changes. For example, you heat a raw egg to cook it. The cooked egg cannot be changed back to a raw egg again.... View Article
Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, to change its velocity, at a constant rate.... View Article
Based on the convention concerning line density, the electric field is greatest at locations closest to the surface of the charge and least at... View Article
In a 1-dimension plane, electric fields can be added according to the relationship between the directions of the electric field vectors. If... View Article
Yes, Earth has an electric field. The electric field of the Earth is the consequence of the Earth having a net negative charge due to charge... View Article
Faraday cage blocks the effects of an external field on its internal contents or the effects of an internal field on the outside environment.... View Article
In Physics, uncertainty is a range of values which likely encloses the true value. Uncertainty is categorized in the following two ways:... View Article
