I did a lab on Simple Harmonic Motion using a pendulum. I found that the length alters the period of a pendulum. In the lab, we took a pendulum and changed the amplitude, added mass, and changed the length.

I'm having a lot of trouble thinking of SOEs (sources of error). Anyone have any ideas or can lead me in the right path? I'm really bad at Physics, so I'm still trying to figure this out. Thanks!

I was recently hospitalized due to my very first severe attack with colitis. I have always suffered along with this ailment throughout my childhood and now well into my 50's. However, it has always subsided with a common sense diet etc but no medication. This time around I could do nothing to stop the pain and even had intestinal bleeding. The doctor released me from the hospital with a very restricted diet. I am on 2 courses of antibiotics and pain killers. I have been home for 3 days and am just beginning to feel better. I have just started eating solids like baby food, jello, toast, cottage cheese etc. Can I ever try chocolate or any of the other foods I so love again? I will be going for a colonoscopy soon and have made an appointment with another doctor. My sons have Crohn's desease. This seems to run in our family. What else can I expect from this illness?

i know that when you scientist set about your work that god is left out of the equasion,so i am going to leave science out of the equasion, this may be rediculess but i am only guessing. if god has made all things in the spirit before they become solid flesh like a knew born babe, the spirit of the child enters the body and becomes encased, this has been done to a certain extent by water in mums womb where this plan of life comes together. If the earth was made in the spirit first what solidified the spirit earth, into solid matter, could it have been rainwater that solidified the spiritual earth. i represent this by using plaster of paris, fine particles add water and it solidifies.The spirit is fine particles and had to be solidified some how.
