Explanation:
As global awareness of air pollution rises, so does the imperative to provide evidence-based recommendations for strategies to mitigate its impact. While public policy has a central role in reducing air pollution, exposure can also be reduced by personal choices. Qualified evidence supports limiting physical exertion outdoors on high air pollution days and near air pollution sources, reducing near-roadway exposure while commuting, utilising air quality alert systems to plan activities, and wearing facemasks in prescribed circumstances. Other strategies include avoiding cooking with solid fuels, ventilating and isolating cooking areas, and using portable air cleaners fitted with high-efficiency particulate air filters. We detail recommendations to assist providers and public health officials when advising patients and the public regarding personal-level strategies to mitigate risk imposed by air pollution, while recognising that well-designed prospective studies are urgently needed to better establish and validate interventions that benefit respiratory health in this context.

Answer:
(a) 220.46 Watt
Explanation:
m = 237 g
T1 = 20 degree C, T2 = 100 degree c , t = 6 minutes = 6 x 60 = 360 seconds
V = 120 V, c = 4186 J/kg C
(a)
Heat required to raise the temperature = m x c x (T2 - T1)
H = 0.237 x 4186 x (100 - 20)
H = 79366.56 Joule
Power = Heat / time = 79366.56 / 360 = 220.46 Watt
Answer:
rate= 5000 m/million years
Explanation:
In order to find this rate, we must divide the number of meters it has moved into the number of years it took the plate to move that distance, so we get:
rate= 5000 m/million years.
