To solve the problem, we need to determine how long it will take for the bar to move 1.50 cm along the threaded rod. Here are the steps to find the solution: ### Step 1: Understand the Threading of the Rod The rod has a threading of 12 turns per centimeter. This means that for every 1 cm of the rod, there are 12 complete turns of the thread. ### Step 2: Calculate the Number of Turns Needed to Move 1.50 cm To find out how many turns are needed to move 1.50 cm along the rod, we can use the threading information: \[ ...

An insulated container is filled with a mixture of water and ice at t_c = 0^@C . Another container is filled with water that is continuously boiling at t_h = 100^@C . In a series of experiments, the containers are connected by various thick rods that pass through the walls of the containers (see the diagram). The rod is insulated in such a way that there is no heat loss to surroundings. In experiment 1, a copper rod is used, and the ice melts in T_1 = 2 min. In experiment 2, a steel rod of the same cross section is used, and the ice melts in T_2 = 6 min. How long ( in min) would it take to melt the ice if the two rods are used "in series"?
