Answer :
Final answer:
The weight of the child is 196 N.
Explanation:
The weight of an object can be calculated using the equation w = mg, where w is the weight, m is the mass, and g is the acceleration due to gravity. In this case, the mass of the child is given as 20 kg and the acceleration due to gravity is 9.8 m/s². Thus, the weight of the child would be:
w = (20 kg) * (9.8 m/s²) = 196 N
