ANSWER:
Solution 92GP
Part (a)
Step 1 of 4:
A spider is hanging from the middle of the thread. The thread makes an angle with the horizontal on its both sides. We are going to find the tension in the thread.
The mass of the spider m = 0.16 g or 0.16 x 10-3 kg
The angle between the thread and the horizontal θ = 7.2°
