My science teacher told my class that the worst pain ever is if you break your mastring, becuase then it would go up and form a bugle in your muscle, and it is the most severe pain in the world. Im not sure, but what really is the worst pain anyone can ever feel? Also, on a scale of 1-10 (10 being the highest and 1 being the lowest) what kind of pain would you be in if you broke a bone?Also, how would it feel?

Water is leaking out of an inverted conical tank at a rate of 6000 cm3/min at the same time that water is being pumped into the tank at a constant rate. The tank has height 6 m and the diameter at the top is 4 m. If the water level is rising at a rate of 20 cm/min when the height of the water is 2 m, find the rate at which water is being pumped into the tank.

When I refer to stopping source, I mean the "parent" of all sources. This seems to be illogical and self-contradictary to many scientific thinkers.

A mixture of KCl and KBr weighing 3.595 g is heated with chlorine, which converts the mixture completely to potassium chloride. The total mass of potassium chloride after this reaction is 3.129 g. What percentage of the original mixture is KBr?

(I was told the answer to the above question is 34.8%, but I am still unsure how this number was calculated. Could someone please walk me through the steps on how to arrive at this answer? Thank you!)

Because what i thought might happend is that super massive black holes are like in the center of the galaxy and our whole entire galaxy is getting sucked into it slowly and once it finally sucks up the whole galaxy its slowly releases atom by atom and then maybe the galaxy is recreated after that.

as we know,the gravitational force of sun provides the centripital force;which is needed to any object to perform the circular motion,so it is clear to me that how does the earth move around the sun in the circular path,but to perform the rotational motion about the axis,from where the earth gets angular moment,which is required if you want to make any object spinning about an axis passing through the object.

This is one amazing word problem that gave me a headake so did the other word problem as well... :(
You have been given a death sentence in a foreign country. The night before your execution, you are brought two boxes, one containing fifty red marbles and one containing fifty blue marbles. All the marbles are the same size, weight, and shape. You are told that on the following day, the executioner will be blindfolded and will put his hand into one of the boxes and remove a marble. If the marble is blue, your life will be spared. If the marble is red, it's off with your head.
You can arrange the marbles in the two boxes however you like, but you can't leave out any marbles, and you can't leave either box empty. Also, the executioner is known to take his time choosing a marble, so you can't improve your chances by stacking all the blue marbles at the top.
How can you arrange the marbles in the boxes so as to maximize your chances of keeping your head?





There are ninety-seven birds sitting in a tree. Shotgun Sharon swaggers up to the tree and fires three whole rounds of ammunition at the birds. She kills twice as many in the first round as in the second round, and twice as many in the second round as in the third round. In the third round she kills three birds. How many birds are left in the tree after Sharon fires off the third round?
