The work done by the electric force to move a 1 c charge from a to b is
<em>(the voltage at 'b' compared to 'a') volts .</em>
<em></em>
That's because "volt" means "Joule per Coulomb" .
Brazil is the former Portuguese colony in South America is the largest country in the region today. You can tell because they speak Portuguese (Brazilian Portugese to be specific) and it is also the largest country in South America. These clues can help you see that it is Brazil.
Answer: The poker stick should have low thermal conductivity and high specific heat.
Explanation: For a poker stick that is non flammable, it should have some properties which will not let it heat up faster.
Two properties that satisfy the poker stick are:
- Specific heat
- Thermal conductivity
Specific heat is defined as the amount of heat require to raise the temperature of a mass M by 1 °C. More the specific heat, more amount of heat will be required to raise the temperature of a substance.
Thermal conductivity is defined as the ability of a substance to conduct heat. More thermal conductivity means that the substance will get hot faster as it will conduct more amount of heat.
So, for a substance that should not conduct more heat like the poker stick must have high specific heat and low thermal conductivity.
