question 18 of 25\na television has a mass of 19 kg. what is the weight of the television?\na. 186 n\nb. 217 n\nc. 155 n\nd. 121 n
Answer
Explanation:
Step1: Recall weight formula
Weight $W = mg$, where $m$ is mass and $g$ is acceleration due to gravity ($g = 9.8\ m/s^{2}$).
Step2: Substitute values
Given $m = 19\ kg$ and $g=9.8\ m/s^{2}$, then $W=19\times9.8$. $W = 186.2\ N\approx186\ N$
Answer:
A. 186 N
