Answer 2

Answer:

The percentage change in the rate of the heat radiation from the patch of the skin of the person is 5.4%

Explanation:

Here we have been mentioned that the particular temperature of the patch of skin of a healthy person is found to be 37°C. Due to the viral fever to the person, his person increases by 5.4%

The percentage change in the rate of the radiation of heat from the patch of the skin can be found as below:

Here the temperature increases by 5.4 % therefore the new temperature is:

37°C + 5.4% of 37°C

= 37°C + $\frac{5.4}{100}$ × 37°C

= 37° C + 1.998°C

= 38.998°C

Which is approximately equal to 39°C

Now the percentage change in temperature = $\frac{39-37}{37}$ ×100%

= $\frac{2}{37}$ × 100%

= 5.4%

Therefore the percentage change in the rate of heat radiation from the patch of the skin is 5.4%
