Answer»

Correct option is (B) 43.25

From the data given we assume

load = exponent/log(cycles)

80 = x/log(10000) ⇒ x = 160

40 = x/log(10000) ⇒ x = 160

load = 160/log5000 = 43.25

12530.	Explain why `NH_(3)` is basic while `BiH_(3)` is only feebly basic ?
Answer» Both N in `NH_3` and `Bi` in `BiH_3` have a lone pair of electrons. Since the atomic size of N is less than Bi and N is more electronegative than Bi Hence electron density is more on N in `NH_3` than on Bi in `BiH_3`. Consequently the tendency to donate its lone pair is more in `NH_3` hence `NH_3` is more basic than `BiH_3`.

12550.	The per capita water requirement for hospitals per day is-1. 100-150 Liters2. 150-200 Liters3. 200-250 Liters4. 250-300 Liters
Answer» Correct Answer - Option 1 : 100-150 Liters Concept:- Hospitals are required to ensure whether the water supply is sufficient as per the requirement of the hospital. Health facilities with less than 100 beds require about 350 liters of water per day and hospitals with more than 100 beds require about 400 liters of water per day. Water availability per person is dependent on the population of the country and for India, per capita, water availability in the country is reducing due to an increase in population. As per the Ministry of Housing and Urban Affairs, 135 litres per capita per day (lpcd) has been suggested as the benchmark for urban water supply. So, per capita, water requirement for hospitals per day is 100-150 Liters.
