You are running a calorimetry experiment where you are trying to determine the number of Calories (with a capital C!) in a peanut. You set up your aluminum can of water and take all your initial data, putting it in the table below. Then, you set your peanut ON FIRE You finish filling out your table once the peanut has gone out. How many Calories of heat did your peanut release? Round your answer to two digits after the decimal point.
Initial Mass of Peanut
3.11 grams
Final Mass of Peanut
0.52 grams
Mass of Water
60.7 grams
Initial Temp of Water
22.4 degrees C
Final Temp of Water
75.6 degrees C

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
