Is the sciencetjfic law and security theory the same?
TRUE
Answer:
Speed of sound inside metal is ≅ 8200 
Explanation:
Given :
Length of metal bar 
m
From general velocity equation,
Where 
speed of sound in air = 343
For finding time from above equation,
sec
Since pulses are separated by 
sec
So we take time difference,
So speed of sound in metal is,
Answer:
The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms.
Explanation:
Answer:
Resistivity, electrical resistance of a conductor of unit cross-sectional area and unit length.
Explanation:
A characteristic property of each material, resistivity is useful in comparing various materials on the basis of their ability to conduct electric currents. High resistivity designates poor conductors.
