Kayley is playing a video game. Her character in the game is a mouse which must forage for food. The goal is to find all the food in an area without being eaten by predators. If we view foraging in this manner as a problem solving process, then what might be the operators in this problem? Question 27 options: a) The set of intermediate states that the mouse tries to achieve before achieving the goal, such as finding all the food in a certain area. b) The set of actions that the mouse can take in a given situation, such as digging for food or moving to a new area. c) The set of all possible states of the game world, including the mouse's location, the location of food, the location of predators and so on. d) The set of requirements for the goal state, including having all the food and being alive and uneaten.

A oceanography team realizes they can relate the density $\rho_{sea}$ of deep, cold seawater to the speed of traveling waves in a cable connecting the weight back up to their boat. To do this experiment, they choose a weight with a density $\rho_{weight} = 9,764$. When they hang the weight from the cable in air, it produces a wave speed of 32.17 m/s. Then, they lower the weight down into the deep ocean. At a depth of 2.2 km, the density of seawater increases up to 1,172 kg/m$^3$. What is the velocity of waves on the cable when the weight is at this depth? Give your answer in units of m/s.
