Me with question !

explain how the sieve of eratosthenes can be used to find composite numbers.

Step-by-step explanation:

It is more frequently used to find primes, oddly enough.

Write down the first 25 numbers.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

Start with 2. Use your eraser and jump to 4. Erase it because 2 will divide into 4. Leave 5 alone. 2 won't go into 5. But it will into 6. Erase six. Leave 7. Go to 8 and erase it. Leave 9 erase 10. Leave 11. Erase 12. Leave 13. Erase 14. Erase 16,18,20,22,24,26,28,30 all for the same reason. Two will divide into each of them.

Start with 3 can't do anything. 3 stays 6 is gone erase 9 . 12 is gone. Erase 15. 18 is already gone. Erase 21, 24 is gone. Erase 27. 30 is gone already.

Do the same with 5, 7, 11, 13,17,19,23 (you do run out of numbers to erase)

The sieve leaves behind the primes.

Anything you have erased is a composite.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
