question 2 of 25\na computer has a mass of 3 kg. what is the weight of the computer?\na. 29.4 n\nb. 77.2 n\nc. 3 n\nd. 288 n
Answer
Explanation:
Step1: Recall weight formula
Weight $W = mg$, where $m$ is mass and $g$ is acceleration due to gravity ($g = 9.8\ m/s^{2}$ on Earth).
Step2: Substitute values
Given $m = 3\ kg$ and $g=9.8\ m/s^{2}$, then $W=3\times9.8$. $W = 29.4\ N$
Answer:
A. 29.4 N
