Final answer:

The weight of the glider with a mass of 4.9 grams is approximately 0.048 N.

Step-by-step explanation:

The weight of an object is calculated by multiplying its mass by the acceleration due to gravity (g). On Earth, the acceleration due to gravity is approximately 9.8 m/s². Given that the mass of the glider is 4.9 grams, we can convert it to kilograms by dividing by 1000: 4.9 grams = 0.0049 kilograms.

To calculate the weight, we use the formula: weight = mass * g. Substituting the values, we get: weight = 0.0049 kg * 9.8 m/s² = 0.04782 N.

Rounding to the appropriate number of significant figures, the weight of the glider is approximately 0.048 N.
