Binding energy, amount of energy required to separate a particle from a system of particles or to disperse all the particles of the system.
From reliable sources in the web, it may be searched that the specific heat of copper is approximately equal to 0.385 J/gC. The amount of heat that is required to raise a certain amount by certain number of degrees is given in the equation,
H = mcpdT
where H is heat, m is mass, cp is specific heat, and dT is temperature difference. Substituting the known values,
186,000 J = (m)(0.385 J/gC)(285C)
m = 1695.15 g
The thermal energy heats up the energy in the ice cube causing it to melt and cool off the drink slightly.
the equation of the parabola is given as 
. D
<h3>How to find the parabola</h3>
Given the focus(6,2) and the directrix, y = 0
Use the formula
= (y - 0)
Find the square of both sides, square root is removed from the side with it and square added on the other side
Expand the expression and bring all terms to one side
= 
Collect like terms
Make 'y' the subject of the formula
Divide through by 4 and substrate 4 from 40 to give a perfect quadratic equation
Divide factor by 4 to give 1
Simplify the expanded quadratic equation
, we have 
Then insert in place into previous equation
Thus, the equation of the parabola is given as

Answer:
See the answer below
Explanation:
A decrease in pressure would see a shift in the equilibrium to the left-hand side of the equation.
<em>According to a particular chemical principle, a system in equilibrium that has one of the constraints affecting reactions applied or removed would experience a change in the equilibrium position so as to annul the effects of the application/removal of the constraint.</em>
In this case, 2 moles of NO2 is present on the left-hand side as opposed to 1 mole of N2O4 on the right-hand side. A decrease in pressure will create more space for the formation of NO2 on the left-hand side. Thus, the equilibrium will shift a bit to this side so as to annul the effects of the decrease in pressure.
