Write a class to represent dates (i.e., day/month/year). Add methods that should perform operations such as determining the number of days between two dates, add two dates, determining the number of months between two dates and determining the day of the week that a particular date falls on. Write a test class to confirm that your date class works.
A block attached to a spring is made oscillate with initial amplitude of 8.0 cm after 2.2 minutes, the amplitude decrease to 5.0 cm calculate

Derive an expression for the logarithmic decrement of a damped oscillator
In an electric lamp, 2.50C pass through each second. How many electrons does this represent?
A metal ball is supported on an insulating stand. You wish to place a positive charge on the ball, but you have only an object that carries a negative charge. Explain how you could accomplish your aim.
In an electric lamp, 2.50C pass through each second. How many electrons does this represent?
Two small charged metal spheres are placed 20cm apart in air. If they have +20 x 10-6 C and +4 x 10-6 C charges on them respectively, what force acts on them? What is the electric field intensity halfway between them?
1. A charge of Q1 of 2 x 10-6 C is placed on a line between two charges Q2 of 1 x 10-6 C and Q3 of -6 x 10-6 C. Q1 is 10 x 10-4 m from Q2 and 20 x 10-4 m from Q3. What is the net force on Q1?
