The resistance of the sample is 
Explanation:
The relationship between resistance of a material and temperature is given by the equation

where
is the resistance at the temperature 
is the temperature coefficient of resistance
For the sample of nickel in this problem, we have:
when the temperature is 
While the temperature coefficient of resistance of nickel is

Therefore, the resistance of the sample when its temperature is

is

Answer:
Copper
Explanation:
Capacitance is directly proportional to dielectric constant
Aluminium and zinc are highly reactive and have high dielectric contact.
Copper has less dielectric constant hence capacitance will decrease
No, because sometimes you have to stop at stop signs and stop lights.
Bottom of the distillation flask
Explanation:
The solid in the mixture to be separate would be found at the bottom of the distillation flask.
Distillation is a separation technique for differentiating the components of mixtures based on the differences in their boiling points.
- Distillation is used to recover solvents from solution.
- The solutes are then left behind in the flask as the solvent boils out as vapor.
- The solution is boiled in a distillation flask to vaporize the solvent.
- The vapor is made to condense back into liquid by means of a condenser.
- The pure liquid called distillate is collected in the receiver.
- The solute which is the solid remains in the distillation flask
