True- B. False### ExplanationThe questions provided are designed to test knowledge of basic physics principles, specifically relating to forces and the interaction between objects. Each question requires an understanding of concepts like gravitational force, reaction force, and the use of instruments to measure physical quantities. **Educational Content: Understanding Forces in a Stack of Objects**A high school student visits the local electronics store to purchase supplies for her science project. She finds what she needs and stacks her planned purchases on the check-out counter. Her stack of purchases consists of a 400-gram robotics kit, a 300-gram multi-meter, and a 200-gram soldering tool, as shown in the figure below. The entire system is at rest and remains at rest.**Diagram Explanation:**The diagram illustrates three items stacked one on top of the other:- **Soldering Tool** (top): 200 grams- **Multi-Meter** (middle): 300 grams- **Robotics Kit** (bottom): 400 gramsThese items are placed on the **Check-out Counter**.**Questions and Calculations:**15. **The soldering tool has a weight of:** - A. 1960 N - B. 200 N - C. 2.00 N - D. 200 kg - E. 1.96 N16. **The multi-meter pushes down on the robotics kit with a force having magnitude:** - A. 2.94 N - B. 2940 N - C. 29.4 N - D. 4.90 N - E. 500 kg17. **The robotics kit pushes down on the check-out counter with a force having magnitude:** - A. 8.82 N - B. 400 N - C. 3.92 N - D. 900 kg - E. 8820 N**Note:** The weight of the objects is calculated using the formula \( W = mg \), where \( m \) is the mass in kilograms and \( g \) is the acceleration due to gravity (approximately \( 9.8 \ m/s^2 \)).
