If an object has a mass of 20 kg on a planet with a force of gravity of 4 m/s2. What is the object's weight?
**Remember** W=mg
a
0.2 N
b
200 N
c
5 N
d
80 N
The weight is:
W = mg = (20 kg)(4 m/s^2) = 80 N
Answer: d) 80 N

The Redheads prepared large catapults and lines of archers that stood ready Redworn cried aloud "prepare ready to fire" The archers prepared their bows facing the walls but suddenly Nethstel cried aloud and the three great catapults fired with fire ablaze on the rocks they fell crushing many redheads fire and dust flew through the air the redheads ran and those who could not make it were crushed then the Redheads answered with flying rocks and singing bows the already ruined walls fell apart where the heavy rocks of the redheads landed archers fell from the walls and others were crushed.
"We must destroy their catapults before we are destroyed" Cried Nethstel " aim for their catapults crush them"
The great catapults fired fire hissed through the air and crushed some redheads catapults wood and dust flew through the air knocking down many redheads the redheads countered their heavy rocks crushing many soldiers. The redheads rocks were covered in red paint.
"Look" Said Pumperin "They love red so much that they must paint their boulders red"
Nethstel cried again "fire the catapults" the catapults fired knocking many red heads down Hunaruan suddenly cried
"Where are the foot soldiers" he cried "the redheads are ambushing us" suddenly many redheads fell upon the city crying aloud they struck the large gates but to no avail.
"Archers fire" cried Nethstel "bring the redheads down"
Arrows flew knocking redheads down Redworn cried "fire the catapults"
The redheads suddenly fired their few remaining catapults fire flashed and the great statue of Nubarana the first fell crushing soldiers the head rolled pushing the gate open it rolled over the redheads cruising them the redheads began to run in the soldiers all ran to the gate fighting the redheads but the strong redheads easily beat down the Rowbins. Nethstel cried again and the archers fired. Then Nethstel ran down the stairs he drew his sword and slashed a redhead down. Hunaruan ran over to the gate he stood by the gate slashing down the redheads that neared him.

The Redheads had prepared large catapults and lines of archers that were ready. Redworn cried out, "Prepare! Ready to fire!" The archers faced the walls with their bows, but suddenly Nethstel shouted and the three great catapults fired with fire ablaze. The rocks fell, crushing many Redheads. Fire and dust flew through the air. The Redheads ran, and those who could not make it were crushed. Then the Redheads answered with flying rocks and singing bows. The already ruined walls fell apart where the heavy rocks of the Redheads landed. Archers fell from the walls and others were crushed.
"We must destroy their catapults before we are destroyed," cried Nethstel. "Aim for their catapults! Crush them!"
The great catapults fired. Fire hissed through the air and crushed some Redhead catapults. Wood and dust flew through the air, knocking down many Redheads. The Redheads countered with their heavy rocks, crushing many soldiers. The Redheads' rocks were covered in red paint.
"Look," said Pumperin. "They love red so much that they must paint their boulders red."
Nethstel cried again, "Fire the catapults!" The catapults fired, knocking down many Redheads. Hunaruan suddenly cried, "Where are the foot soldiers? The Redheads are ambushing us!" Suddenly, many Redheads fell upon the city, crying aloud. They struck the large gates but to no avail.
"Archers, fire!" cried Nethstel. "Bring the Redheads down!"

To find the object's weight, we can use the formula W = mg, where W represents weight, m represents mass, and g represents the force of gravity.
In this case, the mass is given as 20 kg and the force of gravity on the planet is given as 4 m/s^2.
To find the weight, we simply multiply the mass by the force of gravity.
W = (20 kg) * (4 m/s^2)
W = 80 N
Therefore, the weight of the object is 80 N, which is option d.
