Solve the problem.The sun is surrounded by an extremely hot plasma called the "corona". The average kinetic energy E of a subatomic particle in the corona can be approximated by the model 
where E is in joules, T is the Kelvin temperature of the corona, and k is Boltzmann's constant, 
At a certain distance above the sun's north pole, a measurement indicates that the average kinetic energy of coronal particles is 0.00 J. Estimate the temperature in this region.
A. 3.0 × 105 K
