Final answer:
The weight of a talisman with a mass of 750 grams is calculated using the formula weight equals mass times gravitational acceleration, which on Earth is approximately 9.8 m/s². After converting grams to kilograms, the talisman weighs 7.35 newtons (N).
Step-by-step explanation:
The question is how much a talisman that has a mass of 750 grams would weigh. To find the weight from the mass, we can use the formula weight (W) = mass (m) × gravitational acceleration (g). Assuming we are on Earth, where the average gravitational acceleration is about 9.8 meters per second squared (m/s²), the calculation would be 750 grams × 9.8 m/s². However, since weight is commonly measured in newtons (N) and the standard unit of mass is kilograms (kg), we need to first convert 750 grams to 0.750 kilograms. The weight then is 0.750 kg × 9.8 m/s², which equals 7.35 newtons (N).
