Answer:
0.5°c
Explanation:
Humidity ratio by mass can be expressed as
the ratio between the actual mass of water vapor present in moist air - to the mass of the dry air
Humidity ratio is normally expressed in kilograms (or pounds) of water vapor per kilogram (or pound) of dry air.
Humidity ratio expressed by mass:
x = mw / ma (1)
where
x = humidity ratio (kgwater/kgdry_air, lbwater/lbdry_air)
mw = mass of water vapor (kg, lb)
ma = mass of dry air (kg, lb)
It can be as:
x = 0.005 (100) / [(100 - 100)]
x = 0.005 x 100 / (100 - 100)
x = 0.005 x 100 / 0
x = 0.5°c
So the temperature to which atmospheric air must be cooled in order to have humidity ratio of 0.005 lb/lb is 0.5°c
Answer:
instances of hazardous practices are not utilizing headlights appropriately, driving unreasonably quick for conditions, closely following, dangerous passing, or path evolving, and so on. Inability to wear a safety belt is a high-chance conduct that frequently makes the results of an impact more terrible.

Answer:
69.62
Explanation:
The calculation of this question is as below:-
Consumption: 187W
Everyday operates: 17hours
cost of electricity: 0.06 per kWh
so, the annual operating cost
= Consumption ÷ kWh × Everyday operates × cost of electricity × total number of days in a year
Annual operating cost = 187W ÷ 1000 × 17h × 0.06 × 365 days
= 69.62
