A ball of mass 625.g traveling 4.00 m/s to the right, has an elastic head-on collision with an identical ball which is at rest. Find the final velocity of each ball.
Four charges, q1 =5.00 x10-7C, q2 = -3.00 x10-7 C, q3 = -2.00 x10-7C, q4 = 6.00 x10-7C, are situated at the corners of a square of side 4.00m. Find the potential at the center of the square?
A point charge of 3.0 nC with a mass of 4.0 g is moved from x=1.0m to x= 1.5m in an electric field of 5,0 N/C with the same direction as the motion of the charge. (a) How much work is done on the charge by the electric force? (b) What is the change in the potential energy of the charge? (c) Assuming that the charge started from rest, what is its speed at x=1.5 m?
Write a python function Count_Freq(A) which take a dictionary containing numbers. The function will return a dictionary containing key as a number and value as frequency defining how many times the number is repeating in the dictionary.
Note:

Let's now try finding a certain digit into an integer! Come and join in on the fun and code with me!
Instructions:
- Input two integers in one single line. The first inputted integer must be within 0-9 only.
- Using loops, identify if the first inputted integer (0-9) is present in the second inputted integer. If it is found, print "Yes". Otherwise, print "No".
Input
A line containing two integers separated by a space.
1·231214238Output
A line containing a string.
YesCreate a program based on the attached output using the do-while loop. Your program will keep asking the user to choose from the Options. And the program exits until the user selects Exit.

The free electrons in a metal are gravitationally attracted toward the earth. Why, then, don’t they all settle to the bottom of the conductor, like sediment settling to the bottom of a river?
