Suppose 8.50 ✕ 10^5 j of energy are transferred to 1.63 kg of ice at 0°c. the latent heat of fusion and specific heat of water are lf = 3.33 ✕ 105 j/kg and c = 4186 j (kg · °c) . hint (a) calculate the energy (in j) required to melt all the ice into liquid water. (enter your answer to at least three significant figures.) j (b) how much energy (in j) remains to raise the temperature of the liquid water? (enter your answer to at least three significant figures.) j (c) determine the final temperature of the liquid water in celsius. °c

The illuminance of a surface varies inversely with the square of its distance from the light source. if the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters, by how many meters should the distance of the surface from the source be increased to reduce its illuminance to 30 lumens per square meter?
