BIO Determining Diet . One method for determining the amount of corn in early Native American diets is the stable isotope ratio analysis (SIRA) technique. As corn photosynilicsizcs, it concentrates the isotope carbon-13, whereas most other plants concentrate carbon-12. Overreliance on corn consumption can then be correlated with certain diseases, because corn lacks the essential amino acid lysine. Archaeologists use a mass spectrometer to separate the 12 C and 13 C isotopes in samples of human remains. Suppose you use a velocity selector to obtain singly ionized (missing one electron) atoms of speed 8.50 km/s, and you want to bend them within a uniform magnetic field in a semicircle of diameter 25.0 cm for the 12 C. The measured masses of these isotopes are 1.99 × 10 −26 kg( 12 C) and 2.16 × 10 −26 kg( 13 C). (a) What strength of magnetic field is required? (b) What is the diameter of the 13 C semicircle? (c) What is the separation of the 12 C and 13 C ions at the detector at the end of the semicircle? Is this distance large enough to be easily observed?

1.0 kg block of ice to melt in the kitchen. The temperature in the kitchen is 31 °C. The ice starts out at 0 °C and takes an hour to melt and reach the same temperature as the surrounding room (31 °C). How much heat does the 1.0 kg of ice/water absorb from the room as it melts and heats up to 31 °C in Joules absorbed?
Latent heat of fusion for water/ice is 334,000 J/kg
Specific heat of water is 4186 J/kg°C
