Python While Loops:.
1. Given a variable s that is associated with non-empty string, write some statements that use a while loop to associate a variable vowel_count with the number of lower-case vowels ("a","e","i","o","u") in the string .
2. Assume the availability of a function is_prime. Assume a variable n has been associated with positive integer. Write the statements needed to find out how many prime numbers (starting with 2 and going in increasing order with successively higher primes [2,3,5,7,11,13,...]) can be added before exceeding n. Associate this number with the variable k.
3. Write some code that repeatedly reads a value from standard input into the variable response until at last a Y or y or N or n has been entered.

Under conditions for which the same room temperature is maintained by a heating or cooling system, it is not uncommon for a person to feel chilled in the winter but comfortable in the summer. provide a plausible explanation for this situation (with supporting calculations) by considering a room whose air temperature is maintained at 20â°c throughout the year, while the walls of the room are nominally at 27â°c and 14â°c in the summer and winter, respectively. the exposed surface of a person in the room may be assumed to be at a temperature of 32â°c throughout the year and to have an emissivity of 0.90. the coefficient associated with heat transfer by natural convection between the person and the room air is approximately 2 w/m2 â‹…â‹… k. what is the ratio of the thermal resistance due to convection to the thermal resistance due to radiation in the summer? what is the ratio of thermal resistances in the winter
