Is it possible that it's because of 2 cans of lemon juice (minute maid) I drink everyday?

I am not really sure, but it happens like 3-4 times a day normally.

Has anyone just tried jumping up and down as high as possible for a period of time?

It seems like that would be the best way cuz I know ankle weights are harmful and lifting weights doesn't give you the right speed.

We burn wood in a furnace that is hooked up to our central air/ht system. One of my children is asthmatic and I would like to know if the heat from the furncace will kill the mold or release it into the air. It goes through the filter system before it reaches the household air. Do I need a special filter? I've heard black mold can be toxic to people, so Will it be incernated or released? Thank you for your help...

The density (Specific Gravity) is a valuable index of chemical composition of alloys. Although, one can calculate the composition of binary alloys of known metals from their densities (Specific Gravities) in straight forward manner, but for alloys having three or more constituents it leads to a mathematically untenable situation as we have more unknowns than the equations. The densities of such multi-component alloys are always associated to a large number of probable compositions. So, mathematically it is not possible to calculate all such probabilities and then to point out authentically with certainty as to which one particular composition does actually belong to the given alloy.



We are making an attempt to establish that the ‘Archimedean method’ still holds good and may be employed successfully to determine the compositions of multi-component alloys by decoding their densities into percent elemental compositions, even without prior knowledge of constituent metals. It further suggests that the densities of alloys hold the characteristic feature – the fingerprints of alloys which may be decoded for forecasting the presence of elements and their compositions in n-component alloys.



The software we have developed successfully decodes the densities of multi-component alloys into elemental percent composition without any prpor knowledge of constituent metals. It automatically detects the presence of the metals in given alloys by decoding their densities.We are making our sincere efforts to compare our theoretical data with experimental results.

May anyone help us financially or otherwise in order to complete this task?

Our findings are likely to publish in forthcoming issue of 'Material Letters' a journal of Elsevier Pblication. For more details regarding our findigs, one may visit the following link to view the abstract free of cost :

Question:
My question is - how difficult of a transition would it be for an AVERAGE intelligence person to switch to science? What steps would I have to take (based on my story below) to accomplish this? Could I still get a bachelors in psychology and (while fulfilling the basic science courses/pre-med courses) go into a science graduate program?

question #1. A rocket is fired at a speed of 75.0m/s from ground level, at an angle of 60 degrees above the horizontal. The rocket is fired toward an 11.0m high wall, which is located in 27.0 m away. the rocket attains its launch speed ina negligibly short period of time, after which its engines shut down the rocket coasts. By how much does the rocket clear the top of the wall?

Question # 2. A marble is thrown horizontally with a speed of 15m/s the tope of a building. when it strikes the ground, the marble has a velocity that makes an angle of 65 degrees with the horizontal. From what height above the ground was the marble thrown?


can you please help me... detailed? please.......

literally, nothing caused the glass dish to bust (well at least not that we know of) but it did, in pieces.

-we had it stored inside the oven when not in use, have been for over a year. (its a gas oven)
-the oven was turned off, in fact, not even used for a couple of days.

out of no where we heard a crashing noise. my sis ran to the windows, and ran to the stove. sure enough, glass all inside the oven. do you think the gas in the oven did it? but i dont get it...the bakeware is meant to be inside the oven cooking your food, why would it just burst for no reason?

and plz no stupid remarks like, the oven is haunted or anything. im looking for scientific reasoning, or if this ever happen to anyone?

thank you
