a) if 50 mL of water at 22.3 degrees C is mixed with 50 mL of water at 47.7 degree C in such a way that no heat is lost to the environment, what will be the temperature of the final mixture?

b) if 50 mL of water at 22.3 degrees C is mixed with 50mL of water at 47.7 degree C in a calorimeter with Ccal= 20.0 J/Degree C, what will be the temperature of the final mixture?

Thank you so much!

I am looking for an aprocimation of how much pressure would be required to fossilize an animal in a few days. If this is not possible please tell me why.
Thank you

i think it boils at 100 degrees in F but what is that in C?

well if you could get me a URL/LINK to how to build a 2 liter bottle rocket ship, that will do. i dont need to worry about flying it. just building and designing it. its a science project for eight grade. hope i gave you enough info.

Some of the "natural" wonders include:

1.) Grand Canyon 2.) Great Barrier Reef
3.) Harbor Of Rio de Janeiro 4.) Mount Everest
5.) Polar Aurora 6.) Paracutin Volcano
7.) Victoria Falls

Maybe it's one of these. Or, maybe you think that some other magnificant natural wonder deserves a shot at the top seven. Let me here your choice... and maybe tell us why you think your pick deserves recognition. It may be just because you think it is "cool". Whatever you pick is your choice...

The scale model was drawn using a ratio of 1 cm : 30 m. Using this ratio, and the scale model dimensions in centimeters, what are the actual measurements of the real pyramid. You will use the real measurements, in meters, to answer questions 2–5 below.

What is the length of one side of the square base (s) in meters? 231 m
What is the slant height of the pyramid (l) in meters? 186 m
Find the perimeter of the base of the pyramid in meters. 924 m


Find the lateral area of the pyramid. 2864.4 m^2


Find the area of the base of the pyramid. 1778.7 m^2


Find the surface area of the pyramid. 4643.1 m^2
I'm right or wrong please if any one can tell me showing the work it will be nice thank youuuuuuuuu

I need good ideas from people that know technology !!!

I just started a Voluntary Organization with a goal to Engineer, Build & Provide Assistance Devices to Seniors that will allow them to stay in their Current Homes for an additional 10 to 20 years.

What are your ideas ? It doesn't even have to be highly technical, sometimes the simple ideas are the best.

Maybe you have an elderly family member or friend and have something that you think would help them.

Even if it is ROBOTIC or a fantasy type item that can not be made yet... any idea will help move us forward to making them into real items to help older people.

You can see some of the ideas on the website :

Thank you for your Answers.

...just wondered what would happen if you were able to manufacture an enclosed metal container that magnetically had a positive charge within it's entire interior wall...and could hold it's structural integrity. Lets say it weighed 50 lbs. in total.
...and then....could you have within this object a metal ball ALSO of positive charge...smaller, of course, and weighing perhaps 5 lbs. As far as I understand, "like-charged" objects will magnetically repel each other...meaning the central object should be in a state of levitation within the larger container...with both inner wall and object having positive charges.
The REAL question is this....if one were to weigh the container with this object within (hovering presumably), would it weigh in at 55 lbs. (the weight of both), or will it weigh in at 50 lbs...just the weight of the container???....since the inner object is effectively levitating?

I am leading a lab in my Advanced Bio class (I'm a senior in high school). I wanted to try to do something other than the 12 standard AP Bio labs. It would be good if it could be done in a class of 20 students . If you don't have an idea, can you think of an interesting topic that I could search for an experiment on?
