A type of material that tries to prevent the flow of thermal energy is called an insulator.
Mass per cubic metre so kg/m3. Temperature may give different results.
The answer is B. magnesium I am pretty sure
Answer:
While the use of the type of transformer in a rectifier depends on the voltage requirement or to meet desired operating conditions, a step-down transformer is used mainly to reduce the voltage. It is used to bring the high AC voltage level to a reasonable value or the desired output voltage.
