Final answer:
The force of gravity on the combined 15 kg system is 147 newtons.
Step-by-step explanation:
The force of gravity (Fg) acting on any object near the Earth's surface can be calculated by the formula Fg = m × g, where m is the mass of the object and g is the acceleration due to gravity (approximately 9.8 m/s² on Earth). To determine the combined force of gravity on the 4 kg box of cream cheese and the 11 kg box of bagels, you add their masses together to get the total mass and then multiply by the acceleration due to gravity.
Total mass (m) = 4 kg + 11 kg = 15 kg
Force of gravity (Fg) = m × g = 15 kg × 9.8 m/s² = 147 N
Therefore, the force of gravity on the combined system is 147 newtons (N).
