light travels from water (n=1.33) into an unknown medium. if the angles of incidence is 30 and the angle of refraction is 24 what is the index of the refraction of the unknown medium

Aball bearing at 220.0 °c is dropped into a cup containing 250.0 g of water at 20.0 °c. the water and ball bearing come to a temperature of 30.0 °c. what is the heat capacity of the ball bearing in j/°c? (hint: how are the algebraic signs of q related for the ball bearing and the water? )
