Francis gently combed through his hair and four hairs came out. which is most likely the age of the four hairs? 6 months 10 months 2 years 4 years

The correct answer is 4 years.

The falling of hair is a common factor but there are certain reasons because of which the hair fall. These reasons can be genetic factors, pollution or unhealthy diet else lack of sleep can be one of the reasons. Naturally, hairs are anagen phase for two to four years and then the phase is changed into telogen and in this phase it rests for about two to four months and then the falls. This place is occupied by the new, growing hair.

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.
