No. In fact, most conductors don't obey Ohm's Law.
For Ohm's Law to apply, the ratio of voltage to current must remain constant for variations in voltage. For many conductors this simply doesn't happen and, for that reason, we call such conductors 'non-linear' or 'non-ohmic'.
No semiconductor's do not obey ohm's laws.
The resistance of a conductor is directly proportional to the resistivity of the conductor. since the resistivity of a conductor is decreases with decrease in temperature hence the resistance.
I hope you mean the thermistor. If so,well it does not obey Ohms law. When current flows through the thermistor its temperature start increasing which reduces the resistance of the thermistor. A reduction in resistance at the same supply voltage will cause the current to increase. Thus it's not obeying Ohms law.
It depends on the value of voltage being applied to the wire in normal use. Voltages up to 750 volts can be used on wires reading as low as .5 meg ohms. Engineers like to see 5 meg ohms on conductor readings.
The resistance of a conductor is directly proportional to its length, hence increasing the length twice will increase the resistance twice as well. Therefore the resistance will be 2*10 = 20 Ohms

This depends, you have amperage which is how much pressure of electricity is being pushed through the conductor. Next is what kind of conductor, the matters because of ohms, which is how much resistance is caused by the conductor
Very few conductors obey Ohm's Law, and its the rise in temperature of the conductor when current flows though it that prevents it from obeying Ohm's Law. Some alloys, such as constantan, obey Ohm's Law over a limited range because, over that range, changes in temperature don't affect their resistance. It's really time that we stopped teaching Ohm's Law, as it is not universal, and applies to very few conductors and hardly any electronic components!

The property of a conductor that impedes the flow of charge is called resistance. It is measured in ohms and depends on factors like the material, dimensions, and temperature of the conductor.
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor. It is represented by the formula I = V/R, where I is current, V is voltage, and R is resistance.
The condition that limits the flow of electrons in an electric circuit is called resistance. Resistance is measured in ohms and is caused by factors such as the material of the conductor, its length, and its cross-sectional area.
the vibration produced in the coil of a speaker is due to current passing through it hence it obey ohms law
The resistance of a conductor is directly proportional to its length, hence increasing the length twice will increase the resistance twice as well. Therefore the resistance will be 2*10 = 20 Ohms
A conductor with a resistance of 5 ohms allows electric current to flow through it with relatively low resistance. The specific materials and dimensions of the conductor determine its resistance; for example, copper or aluminum wires can have different lengths and cross-sectional areas that influence their overall resistance. In practical applications, a conductor's resistance affects how much current can pass through it for a given voltage, as described by Ohm's Law (V = IR).
