Guys does the format of article remain same ? or it varies with the Content ?
If it remains Same then , Is the following Structure Correct ?
1. Title
2. Question to create interest
3. Transition
4. Advantages with supports
5. Disadvantages with supports
6. Conclusion

• loss in oxygen

help what is the answer of part d ??

does any one have chemistry notes

Find time for one complete wave to form which is the time period T = 1/f ; T =1/0.5 = 21
Now time for one wave is 2s but there are 1.5 waves on the screen
So time for 1.5 waves to form is 1.5*2 = 3s
