1-5 The ball is tied to a string to whirl it having a radius of 40.0 cm at a velocity of 2.5 m/s. What will be
the acceleration of the ball?
Determine the enthalpy for the reaction CaCO3 - CaO + CO2
Given data:
2Ca + 2C + 3O2 - 2CaCO3 enthalpy= -2,414 kJ/mol
C+ O2 - CO2 enthalpy= -393.5 kJ/mol
Ca + ½O2 - CaO enthalpy= -1,270 kJ/mol
There are multiple (T) bookstores in the area. Each shopkeeper has a list of B integers that represents the cost of each book. You have different pocket money(P) for each bookstore. Write a program to calculate the maximum number of books you can buy in each store with the corresponding pocket money.
Explanation
Given P = 600 and B = [120, 140, 110, 180, 120, 110] with a pocket money of 600, we can buy the books at index 0,1,2,4,5 , whose sum is 120+140+110+120+110 is equal to P.
Given P = 300 and B = [120 110 1300 130] with a pocket money of 300, we can buy the books at index 0,1 whose sum is 120 + 110 and is less than P.
Given P = 100 and B = [220 1000 500 2000] with pocket money of 100, we can't buy any book. So the output should be Retry.

A Carnot heat engine uses a hot reservoir consisting of a
large amount of boiling water and a cold reservoir consisting of a
large tub of ice and water. In 5 minutes of operation, the heat
rejected by the engine melts 0.0400 kg of ice. During this time,
how much work W is performed by the engine?
