Suppose the temperature of a COVID positive patient is recorded as Tbody = 40ยฐC.
Determine the wavelength at which the radiation emitted from the body reaches its peak.
a. The points ๐ด,๐ต and ๐ถ have co-ordinates (โ1,2),(1,1) and (2,3) respectively. Sketch the triangle ๐ด๐ต๐ถ .By calculating the lengths of the sides of this triangle, determine if it is scalene, isosceles, or equilateral.
b. Find the distance ๐๐ต, where ๐ is the midpoint of ๐ด๐ถ, and hence find the area of the triangle ๐ด๐ต๐ถ.

The line joining the point ๐ด (4,6) ๐ก๐ ๐ต (๐,โ3) has a gradient of 3. Find the value of ๐.
๐ and ๐ are the points (3,1) and (โ2,โ9) respectively. Calculate:
a. The distance ๐๐
b. The midpoint of the line joining ๐ to ๐
c. The gradient of the line ๐๐
d. The gradient of a line perpendicular to ๐๐
Artificial Mouse population satisfying the following conditions :
i. Two mouses are born one by one in 1st and 2nd months respectively. This newly born pair of mice build the initial population.
ii. These mice can mate at the age of 2nd month such that this mice pair brings another pair of mice in the 3rd month. So, in this way the mouses produced in a particular month will be equal to sum of mouses produced in the previous 2 months.
iii. If the a and b are produced in the 1st and 2nd months to form an initial population there will be a + b mouses in the 3rd month.
iv. These mice are immortal. They will not die.
Write a python function population-series(a, b, n) which takes the population as a ,b and a
positive integer number 'n' as number of months and returns no. of mouses produced in each month till the nth month in string format using recursion.
How many strings of length n can be formed from the English alphabet ?
