Answer :
Answer: 78 N
Explanation: Weight is the downward force acting on an object due to gravity.
[tex]w=m\times g[/tex]
w= weight of an object
m= mass of object
g= gravity = [tex]9.8 ms^{-2}[/tex]
[tex]w=8kg\times 9.8ms^{-2}=78.4kgms^{-2}=78Newton[/tex]
[tex](1kgms^{-2}=1N)[/tex]
78. g on earth is 9.8 m/s^2 so F=ma and plugging in gives you F=(8kg)(9.8m/s^2) which is closest to 78 N.
