Answer:
They are conductors/conductive. Materials that can transfer thermal energy well are conductive.
Explanation:
Similarity : inverse square law for strength of force compared with distance.
Electrical power, in watts = (voltage, in volts) x (current, in Amperes)
In series with the circuit, so for it pass the current to be mensured.
Letter A
If you notice any mistake in my english, please let me know, because i am not native.
The wave speed completely depends on the characteristics and properties of the medium . . . physical properties for mechanical waves, electrical properties for electromagnedtic waves.
So if you want to change the speed of a wave, you have to change the medium . . . shoot it through some different kind of stuff. <em>(B) </em>
