Let's dive into Question 2 from your test. Here's a breakdown of each part of the question:

Question 2:
Two blocks with mass 2 kg and $M$ kg are connected with a light, inelastic string. The string moves over a light, frictionless pulley. The blocks are initially at rest. The static coefficient of friction ($\mu_s$) between the 2 kg mass and the surface of the table is 0.3.

1. 2.1: State Newton's third law in words.
   Answer:
   Newton's third law states that for every action, there is an equal and opposite reaction. This means that if object A exerts a force on object B, object B exerts a force of the same magnitude but in the opposite direction on object A.

2. 2.2: Calculate the tension in the string.
   To calculate the tension, we need to consider the forces acting on both blocks. Let’s solve this step by step.

3. 2.3: Calculate the minimum value of $M$ that will cause the blocks to move.
   To calculate this, we balance the forces and use the static friction coefficient to find the minimum mass $M$ required to overcome the friction.
