Greetings!
The answer would be ~ Gold. All metals are good conductors. But some however may be slower than others. Gold is not that great of a conductor, but is the best choice on here.
Hope this helps!

Answer: The correct answer is-15 Volts.
Explanation-
Voltage of a battery can be defined as the difference in electric potential that lies between the positive and negative terminals of a battery.
It can be calculated using Ohm's law, which states that the electric potential difference between two points on a circuit is equal to the product of the current that flows between the two points (I) and the total resistance that sis present between the two points. It can be mathematically depicted as-
ΔV = I • R
Putting the value of 'I' and 'R', we get-
ΔV = 5 X 3
= 15 V
Answer:
The materials with which the lab group are to use for the model includes;
i) A candle
ii) A match
iii) A strip of cloth
iv) Tongs
v) A metal can
The processes the lab group are to model are;
a) Conduction
b) Convection
c) Radiation
The procedure the lab group can use to do this is outlined as follows;
1) Tie the piece of cloth around the metal can with a strip of the cloth extending past the bottom of the can
2) Hold the metal can in with the aid of the tongs
3) Light the candle with the match
4) Place the metal can over over the burning candle so that it does not touch the flame
5) While holding the can with the tongs, ensure that the strip of cloth hanging by the side of the can does not come in contact with the flame
Conduction
Conduction heat transfer is observed by the rising temperature of the tongs that is in the contact with the can
Convection
Convection heat transfer is observed by the rising temperature of the can that is placed in the path of the rising convection current from the candle wax
Radiation
Radiation heat transfer is observed by the shrinking of the piece of cloth placed beside the candle flame
Explanation:
<span>You could easily define it this way. This would be valid. But for most of history it was unclear when a baby was conceived, so it would be silly for someone to say their baby was 9 months old when it was actually born at only 8.5 months. Days of conception similarly would not be a good substitute for birthdays because no one would know them. Then in general it was much easier to mark someone's age as when they came into the world as an independent being, and this tradition is far too entrenched (and simple and easy to handle and universal for people in poor countries etc) to think we would at all gain from now finding exactly the date of conception and counting age from that point.</span>
