How rockets engines work and relate on the third law of motion?
Rockets work on the conservation of vector energy, cP. 0 = dcP/dr = cdP/cdt=dP/dt = d(mV)/dt = mdV/dt + Vdm/dt=0 Thus, mdV/dt = -Vdm/dt, or (dV/dt)/V = -(dm/dt)/m. The Rocket's mass accelerates at the rate of the mass changes dm/dt.
How do you calculate net force equals speed equals velocity equals momentum equals acceleration equals?
Force (F) F = m.a and since a = dv/dt thus F = m.dv/dt Momentum (p) p = m.v and since a = dv/dt thus p = m.a.dt By switch dt from R.H.S. to L.H.S we get dp/dt = m.a thus F = dp/dt
What two factors are involved in determining the exact pH of a buffer?
The molarity of the buffer and the hydrogen concentration of the buffer.
What is the difference between a concentrated buffer and a diluted buffer?
The concentration.
What are the three buffer systems?
the three buffer systems are NaHC03 The 2 other buffer systems are H2C03 and HC03 . THANK YOU !

What is derivative of cot t dt?
d/dt cot (t) dt = - cosec2(t)
How does Huygens find the acceleration in uniform circular motion?
a = dv/dt =d(vet)/dt =dv/dt *et+det/dt *vwith det =...
How do you build definition lists?
<dl> definition list <dt></dt> definition tag <dd></dd> data definition <dt></dt> <dd></dd> </dl>
Can you have a zero velocity and zero displacement?
Yes, dD/dt = d0/dt = 0 thusDisplacement D=0 and Velocity dD/dt=d0/dt = o.
If y equals x cube plus 2x and dx over dt equals 5 what is dy over dt when x equals 2?
y=x3+ 2x, dx/dt=5, x=2, dy/dt=? Differentiate the equation with respect to t. dy/dt=3x2*dx/dt Substitute in known values. dy/dt=3(2)2 * (5) dy/dt=60
