Answer:

The polar coordinates of }\left(2,\:2\sqrt{3}\right) are \left(4,\:\frac{\pi }{3}\right).

Step-by-step explanation:

To convert Cartesian coordinates \:\left(x,\:y\right) to Polar coordinates \:\left(r,\:\theta \right) apply:

r=\sqrt{x^2+y^2}\quad \theta =\arctan \left(\frac{y}{x}\right)

x=2\\\\y=2\sqrt{3}

r=\sqrt{x^2+y^2}\\r=\sqrt{2^2+\left(2\sqrt{3}\right)^2}\\r=4

\theta =\arctan \left(\frac{y}{x}\right)\\\theta=\arctan \left(\frac{2\sqrt{3}}{2}\right)\\\theta=\frac{\pi }{3}

The polar coordinates of }\left(2,\:2\sqrt{3}\right) are \left(4,\:\frac{\pi }{3}\right).

How does temperature affect phase changes?
Y_Kistochka [10]
Answer. Temperature affects phase change by slowing down the movement in between the atoms, thus causing a change in kinetic energy, which in turn causes the atoms to undergo forms of combining or a type of disepersion.
