II don't get this problem. I don't know what the difference is between the ball at the top of its path and when it is at the bottom of its path.

The answer that I got was .000137. I think that is wrong. can someone show and explain to me how I do this?

A ball on the end of a string is cleverly revolved at a uniform rate in a vertical circle of radius 85.0 cm. Its speed is 3.90 m/s and its mass is 0.300 kg.

What is the tension in the string when the ball is at the top of its path? What about when it is at the bottom of its path.

The Rhode Island based southern New England Giant Pumpkin Growers club is part of the Great Pumpkin Commonwealth, a kind of world sporting authority for growers. Each year, the club complete at 25 weigh-off in North America and one on Ireland... At the (2005) weigh-off, Rhode island pumpkin took first place , setting a new England record at 1443 pounds, just 26 pounds shy of the world record earlier that year by Pennsylvania grower. A Massachusetts pumpkin came in second at 1333 pounds. Another Rhode Island pumpkin , at 1312 pounds, was heavier then expected, earning third place by 1 ½ pounds.... The Rhode Islander’s top 10 averaged 1174 pounds per pumpkin, topping the charts of the Great Pumpkin Commonwealth... 20 years ago growing a 500 pound pumpkin was considered monumental feat. Now giants regularly up the scale at 1200 to 1400 pounds, 15 feet to 16 feet around, bringing within sight the previously incomprehensible a 1-ton pumpkin.
(1) weights are given for only two of the top ten pumpkins entered from Rhode Island. Write and solve an equation to determine the average weight of the other eight.
(2) Determine the following using the approximate weight of champion pumpkins 20 years ago and the world record weight of the Pennsylvania pumpkin:
a) the average rate of increase in champion weights over the past 20 years
b) the year that we could expect the first 1-ton pumpkin, if growth continues at the average rate
(3) Circumference is a linear measure , while weight is a volumetric, or cubic, measure. Therefore, the weight of an object varies as the cube of its circumference. Estimate the circumference of a 1-ton ( 2000 pound) pumpkin if a 1400 pound pumpkin measures 16 feet around. Assume that pumpkins are spherical and have the same density.
Please, right everything step by step, thanks !

We did the typical magnesium in HCl experiment in school last week. For the post-lab questions its asks for the "literature" value of the molar volume of hydrogen. Its asks us to find the volume in the book (its not in there!). Does anyone know where I can find this, how to do this, or what it is? I got 8.3L/mol using my "experimental data." Not sure if thats correct.

thanks!

I like the male peacock, many colors to admire from mother nature. I noticed the male birds have all the fancy feathers, while female humans put on the makeup to attract mates.

With NASA announcing plans for a permanent space station to be constructed on the southern pole of the moon, it looks as if that's a viable possibility in the coming years. Just wondering, if there was an established colony on the moon, would you live there?

I would, totally! I think it would be cool as hell!
