← In a well-insulated container of negligible heat capacity, 100 g of ice at -10°C is mixed with 200 g of water at 50°C. The specific heat of ice is 0.5 cal g⁻¹ °C⁻¹, the specific heat of water is 1 cal g⁻¹ °C⁻¹, and the latent heat of fusion of ice is 80 cal/g. The final temperature of the mixture, in degrees Celsius, is ____.A coil of 100 turns, each of area 0.01 m², has a total resistance of 2 Ω, and its ends are joined to make a closed circuit. A uniform magnetic field of 0.5 T passes through the coil, perpendicular to its plane. The field is switched off and falls to zero. The total charge that flows round the coil, in millicoulombs, is ____. →
