### Physics Problem

**2. a)** A spider of mass 0.15 kg hangs motionless from a thread. What is the tension in this thread?

**b)** If the spider now accelerates *downward* at a rate of 2.1 m/s² to catch a fly, what is the new tension in the thread?

#### Explanation:

To solve these parts, consider the forces acting on the spider. When the spider is motionless, the only forces are its weight (due to gravity) and the tension in the thread. When the spider accelerates downwards, tension changes due to the additional force needed for acceleration.
