Answer:
The net decrease in calories after walking 3 hours is 210 cal (if the Gatorade intake is discrete) or 765 cal ( if the Gatorade intake is continuous)
Explanation:
The net decrease N in calories after 3 hours will be
N=Net decrease = Decrease due to walking - Increase because of Gatorade
= 300 - 80*t + 50*t = 300 - 30*t
- if the Gatorade intake is discrete ( 1 gatorade each hour with 30 calories intake , so there is total intake of 30*t at time t) , then for t = 3 hours
Net decrease = 300 cal - 30 cal/hour * 3 hours = 300 cal - 90 cal = 210 cal
Net decrease = 210 cal
- if the Gatorade intake is continuous ( continuously drinking Gatorade during the walk) , then
N = ∫(300 - 30*t) dt = 300*t - 30*t²/2 (integrated between t and t=0)
then for t=3 hours
N = 300*3 - 30*3²/2 = 765 cal
Answer:
Burning of fossil fuels
Explanation:
Over the last 200 years, burning of fossil fuels has been the major source of carbon emission. Here, atmospheric concentrations of 12C, 13C, and 14C refers to the carbon isotopes (12C, 13C and 14C) and therefore the statement refers to carbon emissions. It is now no surprise that carbon concentrations in the atmosphere is responsible for the environmental changes and that fossil fuel burning is the reason behind increased atmospheric carbon concentrations as proven by scientific research.
