Final answer:
To lift an object from the center of the Earth, you would need to calculate the work done against the force of gravity. The work done is equal to the force multiplied by the distance lifted.
Step-by-step explanation:
To lift an object from the center of the Earth, we need to calculate the work done against the force of gravity. The work done is equal to the force multiplied by the distance lifted. In this case, the weight of the 1kg object is approximately 9.8N, and if we lift it from the center of the Earth to the surface, which is approximately 6371 kilometers, the work done would be:
Work = force x distance
Work = 9.8N x 6371000m
Work = 6.23 x 10^7 Joules
