Equal masses of two different liquids, Liquid A and Liquid B, are placed in identical insulated beakers. Liquid A is heated for 150 s150\text{ s}150 s and Liquid B is heated for 450 s450\text{ s}450 s using heaters of the same power. Both liquids undergo the same temperature rise. What is the ratio of the specific heat capacity of Liquid B to the specific heat capacity of Liquid A, cBcA\frac{c_B}{c_A}cAcB?
