The process of evaporation causes MCQ with Answer and Explanation

Explanation:
Rutherford's gold foil experiment (1911) revealed tiny, dense, positively charged nucleus. Thomson discovered electron, proposed plum-pudding. Chadwick discovered neutron. Bohr explained atomic spectra.

Explanation:
TV remote uses IR. Not microwave (microwave oven).

Explanation:
Resistance R = ρL/A, where ρ is resistivity (material property). New length L' = 2L, new area A' = A/2. Thus R' = ρ(2L)/(A/2) = ρ·2L·2/A = 4(ρL/A) = 4R. Resistance scales directly with length and inversely with area. Memory tip: 'Double length ⇒ double R; halve area ⇒ double R; combined ⇒ 4×'. This proportional reasoning problem is frequent in electricity sections of competitive exams. Always verify if resistivity changes (it doesn't here, same material).
