A boy throws a ball of mass 0.293 - kg straight upward with an initial speed of 23m/s. When the ball returns to the boy, its speed is 18.24 m/s. How much work does air resistance do on the ball during its flight?
Solution #1 is a 0.025 M solution of hypochlorous acid, HOCl (Ka = 3.0 × 10–8). Calculate each of the
following quantities for Solution #1.
(a) [H+] in Solution #1
why is beaker ,rather than a conical flask used ,when dissolving the solute.
Salt is often used to melt ice and snow on roads in the winter and the
temperature right now is -4.500ºC. How much NaCl (complete dissociation) would be
necessary to melt 1000kg of ice by bringing down the freezing temperature to -
4.500ºC?
when the solution has been made up ,why is it necessary to mix the contents of the flask thouroughly? what feature of the volumetric flask makes this particularly necessary
Between z=-1.46 and z=2.15

Task 4 make your own experiment and trial .choose your own random variable X and compute for its mean , variance and standard deviation
Construct a class called Rectangle. A Rectangle has both a length and a width (both positive integers). Access to them should be only inside the class and within the inheritance hierarchy. Then implement the following:
A quadrilateral is represented by having Dimensions L and B units. Write a program to create two objects. Initialize one using default constructor and other using parameterized Constructor. Find out the perimeter of the quadrilateral and print it
