Which is true as one gets closer to the center of the earth?

a. The person’s weight increases
b. The person’s weight decreases
c. The person’s weight remains the same
d. The person’s mass changes
e. A new dimension is discovered

As one gets closer to the center of the earth, the person's weight increases. This is because the force of gravity becomes stronger as you move closer to the center of the earth. The person's mass, however, remains the same. Therefore, the correct answer is a. The person's weight increases.

The correct answer is a. The person's weight increases.

As you move towards the center of the Earth, the amount of mass below you increases. According to Newton's law of universal gravitation, the force of gravity is directly proportional to the masses of two objects and inversely proportional to the square of the distance between them. Since the mass of the Earth remains constant but the distance decreases as you move towards the center, the force of gravity acting on you increases.

Weight is the force with which a mass is pulled towards the center of the Earth due to gravity. So, as the force of gravity increases, your weight increases as well. However, it's important to note that your mass remains the same, as stated in option d.

There is no relevance of option e in this context, as weight and mass are sufficiently explained within the framework of our current understanding of physics.
