Answer:
111 seconds
Explanation:
From research, it takes 4200 J to raise 1 kg of body temperature. Which means that specific heat capacity of human body with is; c = 4200 J/Kg°C
We are told that the temperature starts at 37°C and rises to 39.7°C
Thus: Δt = 39.7 - 37 = 2.7°C
Amount of energy required is given by the formula;
q = mcΔt
We are given m = 68 kg
Thus;
q = 68 × 4200 × 2.7
q = 77112 J
From research, the human body is 25% efficient.
Formula for power with velocity is;
P = F × V
F = mg = 68 × 9.81
V = 15km/h = 4.167 m/s
P = 68 × 9.81 × 4.167
P = 2779.72 W
Since the human body is 25%
Then the power of the utilized is;
25/100 × 2779.72 = 694.93 W
Now, we now that;
Power = work done/time taken
694.93 = 77112/t
t = 77112/694.93
t = 111 seconds.
Thus, it will take home 111 seconds to feel exhausted
Do you mean mitosis? If so metaphase.
Observations and Data are FACTS. Scientists use observations and data to draw a conclusion. Observations lead to the recording of data. Scientists ask questions about their observations and then collect data to answer their questions, then they have their evidence. Opinions are not facts, they are simply beliefs or value judgements. Then the scientist should repeat the experiment the results from different scientists should be similar- if the results are not similar and consistent then the experiment must be done again.
