(II) High-altitude mountain climbers do not eat snow, but always melt it first with a stove. To see why, calculate the energy absorbed from your body if you (a) eat 1.0 kg of − 10°C snow which your body warms to body temperature of 37°C. (b) You melt 1.0 kg of − 10°C snow using a stove and drink the resulting 1.0 kg of water at 2°C, which your body has to warm to 37°C.

- A = 13, B = 04, C = 4 A particular radioactive isotope has a half-life of (29.8) years. If the initial amount of the isotope was (28.5) g, how years later will the only (7.20) g remain of this isotope? Give your answer in years and with 3 significant figures.arrow_forwardA particular radioactive isotope has a half-life of (6.5) hours. If you have (24.5) g of the isotope at 10:00 AM, how much will you have at 7:30PM? Give your answer in grams (g) and with 3 significant figures.arrow_forwardSOLVE STEP BY STEP WITHOUT ARTIFICIAL INTELLIGENCE A ship is located in a certain region of the ocean, conducting research that requires knowledge of the sea depth at that point. To do so, it emits a signal with a wavelength of 40 m and a frequency of 30 Hz. If the signal is detected by the ship's radar 8 seconds later, what is the depth of the sea in that region?arrow_forward
