360 J/kg/°C

Explanation:

Heat lost by metal = heat gained by water

-m₁ C₁ (T − T₁) = m₂ C₂ (T − T₂)

-(0.059 kg) C (27.4°C − 221°C) = (0.409 kg) (4186 J/kg/°C) (27.4°C − 25°C)

(11.4 kg°C) C = 4109 J

C = 360 J/kg/°C

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

i would say the answer is food.

hope this !
