Create a class of complex number having two attribute real and imaginary. Write a function to add two complex number and print the result. You need to write parameterized constructor. In main, create two objects of complex number, call the addition function and print the result.
Write a c++ program using constructor overloading to implement the following tasks:
1. Print sides of the cube
2. Print radius and height of the cylinder
3. Calculate and display the volume of the cube
4. Calculate and display volume of the cylinder
Out of 1000 balls, 50 are red and the rest white. If 60 balls are picked at random, what is the probability of
picking up (1) 3 red balls (2) not more than 3 red balls in the sampl
explain how an increase in a person's income can lead to lower consumption of an inferior good such as hamburgers and higher consumption of say steak.
a diver of mass 80kg,steps off a diving board at point a 4,0 m above the level of the water of a swimming pool.the diver enters the water at point b and comes to rest at point c.while the diver falls through the air,an average frictional force of magnitude 172n acts on the diver. the total work done on the diver by no conservative forced while he moves from a to c is -6240j
Iron reacts with atmospheric oxygen to form iron oxide or ferric oxide.Β Look at the chemical equation for this reaction:

Calcium hydride, CaH2, reacts with water to form hydrogen gas:
CaH2 (s) + 2H2O (l) β Ca(OH)2 (aq) + 2H2 (g)
The reaction is sometimes used to inflate life rafts, weather balloons, and the like, where a simple, compact means of generating H2 is desired. How many grams of CaH2 are needed to generate 64.5 L of H2 gas if the pressure of H2 is 814 torr at 32 oC?
