Actually it's

and it says that the energy of an object (E) is equal to the mass (m) of the object multiplied with the squared speed of light (

). This theory says that mass can be turned into energy and energy can be turned into mass. This is one of Einstein's theory of relativity.
The resonant frequency of a circuit is the frequency
at which the equivalent impedance of a circuit is purely real (the imaginary part is null).
Mathematically this frequency is described as

Where
L = Inductance
C = Capacitance
Our values are given as


Replacing we have,



From this relationship we can also appreciate that the resonance frequency infers the maximum related transfer in the system and that therefore given an input a maximum output is obtained.
For this particular case, the smaller the capacitance and inductance values, the higher the frequency obtained is likely to be.
Light waves travel in straight lines when they are travelling in a uniform medium. This is because the waves are travelling at the same speed.
Chemical weathering weakens the outer surfaces of rocks and its primary agent is water. Mechanical weathering is carried out by impact or attrition by water and air.
Both of these forms of weathering combine and cause rocks to obtain a spherical shape.The concentric layers of rock are combined to form structures known as saprolite.
