Three identical blocks connected by ideal (massless) strings are being pulled along a horizontal frictionless surface by a horizontal force F⃗ F → . (Figure 1)The magnitude of the tension in the string between blocks B and C is T T = 3.00 N N . Assume that each block has mass m m = 0.400 kg k g .

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
