    Chemical reaction of 2 H atoms.

    Then how can it gain more velocity when there is more hydrogen atoms
  2. M

    Chemical reaction of 2 H atoms.

    2 H atoms can form a H2 molecule, releasing energy of 5 eV. However, no chemical reaction occurs when 2 isolated H atmos collide! Explain this curious result using the conservation laws. first of all, i don't know what conservation law to use for this question. 2nd i think i don't have much...

    Conservation of Momentum.Boat Question

    Thank you ehild!! i got it!! i learned about integrals.. i just forgot that moment... i spent 2 days and nights for this problem.. and couldn't found a way to solve the problem... u r my life savior!!

    Conservation of Energy. Fountain Question

    Water shoots up from a fountainat a speed of v0 at a rate of dm/dt, and hits a garbage can of mass M suspended in the air. What is the maximum height the fountain can lift the garbage can? First i approached this problem with K.E = P.E i assumed that m at time t = (dm/dt)t so i put...

    Conservation of Momentum.Boat Question

    i kinda get what you are saying... i've never thought of looking at this problem with dv/dn... but i don't get the integration part... so what you are saying is the area under the curve when n=1 and n=N is the velocity achieved by GENIUS?...

    Conservation of Momentum.Boat Question

    A boat of mass m is carrying a load of bricks with a total number of N and mass M, and is floating freely on water. SUPERMAN, in a show of strength, throws the entire load of bricks backward at once with a relative speed of v0. A GENIUS, in a show of intelligence, throws the bricks backward with...
