Question

On which factors does the resistance of a conductor depend? a) only length b) onlg cross-section c) both d) none of these​

Answer 1

Answer:

The resistance of a conductor depends on the length ,area of cross-section of the conductor,its resistivity and the nature of the conductor.

1. More the length of the conductor,more the resistance. Hence resistance of a conductor is directly proportional to the length of conductor.

2. More the area of the cross section less the resistance of the conductor. Hence resistance is inversely proportional to area of cross-section.

3. Resistance also depends on nature of material.

Conductors offer less resistance. Ex- Copper

Insulators offer more resistance. Ex- Plastic.

Hope this helps you with the question! So the answer to the question is (c) both as resistance depends on both length and cross-section of the wire or conductor.

Answer 2

GERMANY

Economic changes and the Zollverein

The struggle of parties and ideologies during the restoration of the old order reflected the beginning of important changes in the structure of the economy and the community. In the long run, the most significant of these changes was the gradual emergence of large-scale industry in Germany. Mechanization, introduced in textile mills and coal mines, spread to other branches of manufacture and influenced the entire economic life of the nation. The transportation network improved with the construction of railroads, steamships, and better roads and canals. Banking institutions and private investors began to transfer their funds from government bonds and commercial ventures to manufacturing enterprises. Factory and railroad owners, financiers, and stockbrokers gradually formed a new upper middle class whose wealth derived primarily from industrial activity and whose growing economic importance encouraged its members to demand greater political influence. Skilled handicraftsmen, who had constituted the bulk of the urban working class, could not compete successfully with the factories.
