When forming a bond, an atom that has 3 electrons in its second shell and a filled first shell will?
Butoxors [25]
Macromolecule polymers are assembled by the connecting of monomers. An -OH group is detached from one monomer and a hydrogen atom is detached from an additional in a procedure named dehydration synthesis in the monomers bond. For every subunit supplementary to a macromolecule in which one water molecule is detached. Macromolecule polymers are broken down by breaking bonds among subunits. This procedure is named hydrolysis and is the opposite of dehydration. During hydrolysis the hydrogen atom is supplementary to one monomer and a hydroxyl cluster to the other and by breaking the covalent bond in the middle of the monomers.

A rocket has initail mass M begins to move from space , with an exhaust constant speed . Find the mass of the rocket while has t
irina1246 [14]

Answer:

m=\frac{m_{0}}{e}

Explanation:

Equation of the rocket is,

m\frac{dv}{dt} =F-v'\frac{dm}{dt}

Here, v' is the relative velocity of rocket.

In space F is zero.

So,

m\frac{dv}{dt} =-v'\frac{dm}{dt}\\dv=-v'\frac{dm}{m} \\v=-v'ln\frac{m}{m_{0} }

Now the momentum can be obtained by multiply by m on both sides.

P=-v'mln\frac{m}{m_{0} }

Now for maxima, \frac{dP}{dm}=0

-v'ln\frac{m}{m_{0} }-v'm\frac{m_{0}}{m }m_{0=0

Now,

ln(\frac{m}{m_{0} } )=-1\\\frac{m}{m_{0} }=\frac{1}{e} \\m=\frac{m_{0}}{e}

Therefore, the mass of the rocket while having maximum momentum is \frac{m_{0}}{e}
