I put a russet potato in a clear plastic container with a dish of water. It had sprouted potato tubers(I think that's the right term) but I waited too long... it now has roots and white fur. Is there a reasonable change I can still get a plant out of it, or should I just start over?

Hello all! Please note this is my first post and I would love to learn the method of calculating the below question... so that I may retain the knowledge and apply it for further models. First... the question. How can I take the following information... and using existing data find the velocity...

Sorry if already asked: Why round, thin, fried potatos often comes out with a "saddle" shape? Thanks. -- lightarrow

If a potato ( or any other food, for that matter) is used as a battery by say, simply inserting two different metal pins in it and connecting it to a load, then does it reduce the nutritional value of potato ? or does it affect the potato negatively in any way ?

There is an interesting video @ Facebook about a potato that is made into a light socket & battery: https://www.facebook.com/HECHOenNUEVOLEON/videos/vb.1388218328082289/1950024855234964/?type=2&theater Now, I see how the generation of energy is done in the way that a "lemon battery" is done...

for my own intressest i thought of a way to look i a potato could survive a 100 metre drop. my hypothesis was abviously no not it will be potato salad when it hits the ground. but my calculations turned against me as far as i know. here are they average potato weight: 0,15 kg height: 100m i...

Homework Statement Hi everyone, i have a problem. My brain is short-circuited, and it seems like i can't find out the simplest chemistry in the world :D We made this experiment where we should determine the sugar content in potato flour. We added amylases to break down the starch to glucose...

Homework Statement So I've been trying to find the specific heat capacity of the potato for a while and keep coming up with an outrageous number (over 700,000 J/kgC) Here's what I've found mass of potato = 0.15kg initial T of potato = 18 degrees C final T of potato = 83 degrees C (is this not...

Hi just made a potato battery, using a cupper coin and zink nails (not connected in any way, just pit in a nail and 3 inches appart a penny), I was just wondering what is the chemistry/physics theory here? Potatoes contain phosphoric acid H3PO4 Is it the acid in potatoes that oxidize...

Hi Guys, I have a Year 11 Project weighted 15% of my year mark due in 5 weeks. For my project I've decided to build a classic combustion potato gun. This gun will consist of pvc piping, barrel, Lantern lighter, any other components and of course hairspray (combustion) Anyways It is still only...

During a conversation a friend and I made a joke that was along the lines of "at least you're not powering it using an orange or a potato" while discussing the power supply for his electric bike. Now I'm wondering...would it actually be possible to power an electric bike using potato batteries...

Homework Statement A Certain potato "canon" consists of a 1.2 m tube with a thin platform inside. The Platform has a negligible mass and is attached to a spring. The spring is 20 cm long when relaxed, and the spring is compressed to a final length of 5 cm when ready to launch a potato. A potato...

hello all, I'm a mechanical engineering student my graduation project is an automatic machine to make the following "converting Potato waste (peel) to bio-ethanol" i need a detailed research about the chemical process until getting ethanol waiting for your help guys , I'm not good chemist...

Launching of a Potato (Involve kinetic and potential energy and an angle!) A potato of mass 210 g is launched from a potato gun, being released from a height of 0.6 m, at an angle of 47o with respect to the horizontal, and with an initial speed of 38 m/s. Assume the effect of air resistance can...

Homework Statement As a participant in a robotic competition, you must launch a potato from a moving cart and strike a target. The potato must reach the apex of flight just as it travels over a screen, then it must pass through the center of an opening in a wall. The cart moves at a steady...

Homework Statement We are given an amount perfume, that has an energy level amounting to 1200 joules. Using this as the fuel, i need to build a potato cannon. How can i build the cannon to maximize the distance the potato travels when shot with this amount of fuel? Homework Equations...

Hello, I built a small potato cannon out of PVC pipe/steel. It's 15.5 cm long, and about 7.6 cm wide on the inside. It's made of 2 parts the barrel and combustion chamber (or as i refer to, "the death chamber"). the "death chamber" is cylinder about 7.6 cm long and 7.6 cm thick. and the...

Homework Statement Suppose (Y1, Y2, Y3, Y4) = (5.2, 6.8, 11.9, 17.0) are the average yields (in tonne/ha) of potato grown in soil with 4 different levels of superphosphate fertiliser, x1 = 1.20, x2 = 1.75, x3 = 2.30, x4 = 2.85. We want to fit the model E[Yi] = \beta1 + \beta2xi + \beta3zi...

I'm reading an electrodynamics textbook and in the preface there is a mention that the number of positive and negative charges in solid objects is extremely precisely balanced, and gives an example, that if there was an imbalance of even 1 part in 10^10, "a potato would explode violently"...

I'd like to hear any ideas on how to determine the eventual winner of "One potato, two potato" without going through the full elimination process. Given n people in a circle, eliminating every 8th person left (which is the process in "One potato, two potato" although every mth person would...

hello, i was wondering what people here would think the best design type for a potato launcher would be. I looked at catapults, ones that use compressed gas, and combustion. firstly, which would be the easiest to make?

I have to find the vertical displacement of a potato shot out of a potato launcher (Gr. 11 Physics assignment). It would make sense (and make this easier) to assume that the potato went straight up and down and I am allowed to assume that air resistance is negligible. My main problem is proving...

I think i must be one, try this simple meal. Roast some potatoes, add one chopped birds eye chili and a couple of branches of oregano and sea salt in the last 10 mins of cooking, put the spuds on a plate then add a tin of mackerel in oil, wow are you in for a treat.

I learned in Ap Bio that a tree's mass comes from carbon.It makes sense, but is it the whole tree or just the trunk of the tree? Cuz I took a Practice Ap test and there involved a question with a piece of potatoe in Water. At first I assumed that it was diffusion or osmosis that occurred but it...

Does anyone else make potato cannons here? Ive made a few with hairspray and 2 pneumatic ones. The best one is over 7 feet tall. I just tested it with a reeses peanut butter cup and it shot it through a 1/4" piece of plywood. I was just wondering if anyone else has made potato cannons or...

Okay. we were given a problem in Physics class regarding a PVC pipe, a potato and a piece of dowling(wood) we were instructed to stick both ends of the pipe into the potato and then (once we had a good plug in either end) push one plug towards the other through the pipe with the piece of...

We did a lab in my class where we put slices of potatoe into solutions with different molar concentrations of sucrose. Now, I am asked to find the osmolarity of the potatoe cores. How do I do this?

can potato skin affect the rate at which catalase in potato discs breaks down hydrogen peroxide? does potato skin contain the polysacharide cellulose?

For a physics project, I really want to do something with an explosion in it, but I can really only come up with one practicable idea - a potato gun. Practicable meaning, an idea that won't cost me much more than 2 hundred dollars in instruments and materials. I plan to find out how much energy...

Hi.. I am currently doing an experiment on Osmosis - Potato Chip, Looking at the effect of osmosis etc, However I was curious whether there was an inner depth to this, So far were ever I look the only defination of Osmosis is higher concentration to lower, but within my prediction I would like...

I have to tie the construction and dynamics of a potato gun with one chapter from my physics book. That's fairly hard to do because a potato gun has much to do with more than one chapter, but my teacher just wants one... Does anybody have an idea on what the best chapter would be? I have...

hey guys what's up? just recently I've been working on this potato battery thingy in chemistry class and the highest i can get it is 15 volts. i knwo there are a lot of variables involved but are there any suggestions that you might think would help achieve a higher voltage? i was thinkin of...
