Answer:
The weight of the parcel is 5 N
Step-by-step explanation:
we know that
Weight can be calculated using the equation:
![W=mg](https://tex.z-dn.net/?f=W%3Dmg)
where
W ----> weight (W) is measured in newtons (N)
m ----> mass (m) is measured in kilograms (kg)
g ----> gravitational field strength (g) is measured in newtons per kilogram (N/kg)
In this problem we have
![g=10\ N/kg](https://tex.z-dn.net/?f=g%3D10%5C%20N%2Fkg)
![m=500\ g](https://tex.z-dn.net/?f=m%3D500%5C%20g)
Remember that
![1\ kg=1,000\ g](https://tex.z-dn.net/?f=1%5C%20kg%3D1%2C000%5C%20g)
To convert g to kg
Divide by 1,000
so
![m=500\ g=500/1,000=0.5\ kg](https://tex.z-dn.net/?f=m%3D500%5C%20g%3D500%2F1%2C000%3D0.5%5C%20kg)
substitute the values in the equation
![W=(0.5)(10)=5\ N](https://tex.z-dn.net/?f=W%3D%280.5%29%2810%29%3D5%5C%20N)
therefore
The weight of the parcel is 5 N
