Body in free fall: acceleration=9.8 m/s^2 When the list is accelerating upward Fnet is upward, therefore:R-mg=ma (R= Normal reaction offered by the surface)R=m(g+a)When body is accelerating downward:fnet is downward:mg-R=maR=mg-maR=m(g-a)In free fallR=m(g-g)R=0

basically used to calculate concentration in a solution.Formulae: Gram equivalent weight/volume of the solution in litres(gram equivalent weight = gram molecular weight/ valency)

Well, the best method would be using the quadratic formula, there's the method of completing the square, but quadratic formula's better.

An object moves in a circle at constant speed. The work done by the centripetal forceis zero because:1. the displacement for each revolution is zero2. the average force for each revolution is zero3. there is no friction4. the magnitude of the acceleration is zero5. the centripetal force is perpendicular to the velocity

Yep, it's analyitcal reasoning. The best way would be to make a table and solve it. It's german.

Maximum distance= infinity Minimum = 25 cm. It is the process by which eye changes its optical power to maintain a clear image of the object.

My answer would be german. See if it matches with yours.

So you want a hard brain teaser! Well, here it is.It's purported that Einstein said 98% of the world's population could not figure out this logic problem. Try your hand at it. Send us an email message if you figure it out. (Use the Contact Us link at the bottom of the page.) And let us know how long it took you!A logical question. Hard Brain TeasersThere are 5 houses each with a different color. Their owners, each with a unique heritage, drinks a certain type of beverage, smokes a certain brand of cigarette, and keeps a certain variety of pet. None of the owners have the same variety of pet, smoke the same brand of cigarette or drink the same beverage.Clues: * The Brit lives in the red house. * The Swede keeps dogs as pets. * The Dane drinks tea. * Looking from in front, the green house is just to the left of the white house. * The green house's owner drinks coffee. * The person who smokes Pall Malls raises birds. * The owner of the yellow house smokes Dunhill. * The man living in the center house drinks milk. * The Norwegian lives in the leftmost house. * The man who smokes Blends lives next to the one who keeps cats. * The man who keeps a horse lives next to the man who smokes Dunhill. * The owner who smokes Bluemasters also drinks beer. * The German smokes Prince. * The Norwegian lives next to the blue house. * The man who smokes Blends has a neighbor who drinks water.Who owns the pet fish?

It is said that he had extra glial cells (reasoning cells) in his brain. :P
