what is the weight of a 1kg mass object on planet earth? 5 newtons 1 pound 9.8 newtons 9.8 pounds 1 newton

Explanation:

Step1: Recall weight - mass formula

Weight (W = mg), where (m) is mass and (g) is acceleration due to gravity on Earth ((g = 9.8m/s^{2})).

Step2: Substitute values

Given (m = 1kg) and (g=9.8m/s^{2}), then (W=1kg\times9.8m/s^{2}=9.8N).

Answer:

C. 9.8 Newtons
