The correct answer is silver metal.
Conductivity measures the ability of a material or a metal to transmit energy, conductivity may be electrical, thermal or acoustical conductivity. The most electrical conductive element is silver, followed by copper and Gold. Silver also has the highest thermal conductivity as compare to any element. However, copper and Gold are more often used in electrical applications since copper is less expensive and gold has a much higher corrosion resistance.
The correct answer for above statement is:
A. Heat energy is released by the substance.
Explanation:
The reverse of deposition is sublimation and therefore generally deposition is termed desublimation. One example of deposition is that the method by that, in sub-freezing air, water vapor changes on to ice while not initial changing into a liquid.It is a process of releasing energy.

Answer:
Explanation:
The Coulomb's law states that the magnitude of the electrostatic force between two charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them:
In this case, we have 
:
Answer:
115.6 J
Explanation:
= mass of the block = 3.7 kg
= final speed of the block = 0 ms⁻¹
= initial speed of the block = 7.9 ms⁻¹
= work done on the block
Using work done - change in kinetic energy theorem, we have
