    How many peaks will there be in an NMR spectrum for Malic Acid?

    1. Homework Statement How many peaks will there be in the NMR spectrum of Malic Acid, HOOC CH2 CH(OH) COOH, WITHOUT D2O as the solvent (i.e. Hydrogens in Hydroxyl groups WILL have corresponding peaks)? 3. The Attempt at a Solution I thought the two -COOH groups will be identical...

    What is the force exerted on an elastic object, on elastic collision?

    I see, thanks, that helps alot

    What is the force exerted on an elastic object, on elastic collision?

    So a more massive object would distort more, and a stiffer object would distort less. For two objects of the same mass, would the stiffer experience a greater maximum force on collision/deceleration, to compensate for the lesser distortion in order to convert the same kinetic energy to elastic...

    What is the force exerted on an elastic object, on elastic collision?

    Homework Statement An elastic object (F = k e) is thrown horizontally at a wall, so it is traveling at constant velocity, which then rebounds elastically (energy conserved). I'm only interested in when the object first makes contact and decelerates to 0ms-1 which will be when the object is...
