Answer:
Explanation:
Given a material with temperature coefficient of resistance <em>c</em>, the equation that relates the resistance 
at temperature 
and the resistance 
at temperature 
is
We want to double our resistance, so 
, thus having:
For this T must be:
which for our values means (with 
, remember to write temperature in S.I., and that for silver 
):

Answer:
As the voltage increases, the current flowing through the circuit increases while the resistance of the resistor remains constant.
Explanation:
Ohm's law states that the current flowing through a circuit is directly proportional to the applied voltage.
V = IR
where;
I is the current
R is the resistance
V is the applied voltage
Based on this law (Ohm's law), as the voltage increases, the current flowing through the circuit increases while the resistance of the resistor remains constant.
The properties of the wave don't determine its speed. The properties of the medium do. You can FIND the speed by measuring the wave's frequency and wavelength.
