You may have heard that potato salad is one of the worst foods to take for a picnic. This is because it doesn’t take very long for it to become contaminated with bacteria. Assuming that you could remove all the bacteria in the potato salad except 10 (virtually impossible) and that bacteria double every 20 minutes – how many bacteria would there be after 3 hours?

I'm not talking about the easy binary compounds where u can just measure the electronegativity. I'm talking about polyatomic ions/atoms with covalent bonds. For CO supercscript 3 with subscript 2- ... How would u know if it's covalent or ionic?

If someone had an invention they wanted to get patented, is it possible to show the invention to a patent attorney to see what potential the invention might have? If so, how safe is it to do that?

Second question. Does anyone know or is a patent attorney that I could e-mail and possibly show designs for an invention?

A Psycho torturer locks your body into a kneeling position under a modified sink.
It is designed so that from the neck up, your head is inside the sink.
Your nose has been stuffed with swimmer's noseplugs so you must breath out your mouth.
One of your hands is handcuffed behind your back but the other is free.
The psycho hands you a high powered screwdriver and turns on the water.

Slowly the water rises to cover your mouth. You cannot breath.


The killer has handed you the screwdriver and he claims "IN ORDER TO SAVE YOURSELF, YOU MUST DRILL INTO YOUR OWN NECK (auto Traechyotomy) so you can breath through your neck.


Do you:

A) Allow the water to drown you

or

B) Drill into your neck so you can breath through the hole?

A street lamp weighs 150 N. It is supported by two wires that form an angle of 120.0 degrees with each other. The tensions in the wires are equal.

a. What is the tension in each wire supporting the street lamp?

b.If the angle between the wires supporting the street lamp is reduced to 90 degrees, what is the tension in each wire.

Please help I need help.
I don't understand it.

So I'm doing an egg drop project for physics, which has many restrictions. First off, it will be dropped downward 8.4m, and there will be a target directly below (the closer you are to the target, the more points, and vice versa). The project must be 250 grams total (egg + whatever used). Also, the teacher stated that the egg is already 60-70 grams, so there is not much to work with. Biodegradable materials are the only materials allowed (no plastic, metal, Styrofoam peanuts, bubble wrap, sponges, other synthetic materials, popcorn). Rubber balloons would also be okay, along with parachutes. So the question is, how should I build it in the way that it drops as close to the target as possible, while still maintaining the maximum weight of 250g? What materials should I use and how should I build it? Thanks
