Question

1. what is the weight of the box in the diagram in number 16? a. 25 kg b. 25 n c. 245 kg d. 245 n

Explanation:

Weight is a force, so its unit should be newtons (N), not kilograms (kg, which is a unit of mass). To find weight, we use \( W = mg \), where \( g = 9.8\ m/s^2 \). If the mass of the box (from diagram 16, assuming mass is 25 kg), then \( W = 25\ kg\times9.8\ m/s^2 = 245\ N \). So the correct unit is N, and the value is 245 N.

Answer:

D. 245 N
