    Quantum mechanics minimum uncertainty

    Hey LHC, thanks for the quick reply :) I know that nm=r and kg=m but how would I sub it into the equation you mentioned?

    Quantum mechanics minimum uncertainty

    URGENT! quantum mechanics question Homework Statement In the lungs there are tiny sacs of air, which are called alveoli. The average diameter of one of these sacs is 0.25nm. Consider an oxygen molecule(mass=5.3x10^-26kg) trapped with a sac. What is the minimum uncertainty in the velocity of...

    How Far from a Conductor Is a Magnetic Field of 3.1x10^-5T?

    Homework Statement 12.5A, 3.1x10^-5 Homework Equations How far from a long conductor passing a current of 12.5A is the magentic field of strength 3.1x10^-5T? The Attempt at a Solution B= uI/2(pi)r r=uI/2(pi)B =(4pi)(12.5A)/ 2(pi)(3.1x10^-5T) = 8.1x10^5m

    Microeconomics - demand, output and profit

    I think my calculations are correct now (if I plug it into my calc correctly lol). After these calculations what equation(s) should I use to find a)How much output will be produced? b)What is the profit at this level? Or is the answer from the above calculations?

    Case Elasticities: Bread & Butter, Alcohol & Gum, etc.

    Oops, yep it's cross elasticity =) I think coffee and tea are compliments but not sure if it's right though... Not sure how to relate the signs with the info. Can you briefly explain what each one means and I'll post the answers to see if I get them right.

    Case Elasticities: Bread & Butter, Alcohol & Gum, etc.

    Identify the case elasticities for the following goods. Explain. a)bread and butter b)alcohol and gum c)peanut butter and jam d)coffee and tea e)margerine and butter a),c),d) --> complements b) --> unrelated e) --> substitutes

    Supply & Demand Impact of SW US/Mexican Freeze: Prices Rise for Imported Produce

    1)the supply decrease due to the bad weather therefore shift to the left b)the price increase I'm not sure if this is relevant but...quantity demanded decreases*

    Supply & Demand: Grain Production Increases and Prices Remain Low

    The demand for the supply of grain has generated a high amount of income for the farmers. Therefore with the amount of income made from the demand of supplies sold, the farmers are able to purchase more land to expand in their grain production. Now since they've expanded with more land for grain...

    Supply & Demand Impact of SW US/Mexican Freeze: Prices Rise for Imported Produce

    jalen answer 1: the demand curve shifts to the right jalen answer 2: Since the demand curve increases, the equilibrium price increased. I'm not sure how to include a graph so I'll explain how it's suppose to look like. The supply will remain the same and the demand will shift to the right...

    Supply & Demand: Grain Production Increases and Prices Remain Low

    Improved grain production methods and increased acreage have more that offset population increases. As a result prices remain low for grain. Describe how this would be interpreted on a supply and demand diagram. Here's what I have so far: -demand decrease, supply increase -price decrease...
