Question

Find the resistance of a hollow cylindrical conductor of length 1.0 m and inner and outer radii 1.0 mm and 2.0 mm respectively. The resistivity of the material is 2.0 × 10⁻⁸ Ω-m.

Answer 1

Find the resistance of a hollow cylindrical conductor of length 1.0 m and inner and outer radii 1.0 mm and 2.0 mm respectively. The resistivity of the material is 2.0 × 10⁻⁸ Ω-m.

1.2 × 10⁻³ Ω

Explanation

Asexual reproduction: one parent, no gametes, offspring genetically identical (clones). Methods: binary fission (bacteria), budding (yeast, hydra), fragmentation (planaria), vegetative propagation (plants).

Sexual reproduction: two parents, gametes fuse (fertilization), offspring genetically unique. Meiosis creates gametes with half the chromosomes; fertilization restores full number.

Asexual is faster but no variation; sexual is slower but creates variation (raw material for evolution). Many organisms do both depending on conditions. Sexual dominant in complex organisms.
