The defect of vision in which the lens becomes opaque is called MCQ with Answer and Explanation

Explanation:
At night land cools quickly, high pressure over land, low over sea, wind from land to sea. Sea breeze opposite.

Explanation:
Transformer voltage ratio: V_s/V_p = N_s/N_p, where N is number of turns. Thus V_s = V_p × (N_s/N_p) = 120 V × (200/100) = 240 V. This assumes ideal transformer (no losses). Step-up transformer (N_s > N_p) increases voltage. Memory aid: 'Turns ratio = voltage ratio'. This direct formula application is frequent in competitive exams. Always verify if transformer is step-up or step-down from turn counts. Note: Current ratio is inverse: I_s/I_p = N_p/N_s for power conservation (V_pI_p = V_sI_s).

Explanation:
Hydrometer measures relative density. Lactometer for milk, but general is hydrometer.
