Select the correct answer.

The weight of an object, w, varies inversely as the square of its distance from the center of Earth, d. When an astronaut stands in a training center on the surface of Earth (3,960 miles from the center), she weighs 155 pounds. To the nearest tenth of a pound, what will be the approximate weight of the astronaut when she is standing on a space station, in orbit 240 miles above the training center?

A.
174.4 pounds
B.
164.4 pounds
C.
146.1 pounds
D.
137.8 pounds

Answer:

D. 137.8 pounds

Step-by-step explanation:

The approximate weight of the astronaut when she is standing on a space station, in orbit 240 miles above the training center will be 146.1 pounds. Option C is correct.

What is weight?

The weight of matter is found as the product of the mass and gravitational acceleration;

Given data;

W is the weight of the astronaut standing in a training center on the surface of Earth

W' is the approximate weight of the astronaut when she is standing on a space station, in orbit 240 miles above the training center

Given condition;

The weight of an object, w, varies inversely as the square of its distance from the center of Earth, d.

W = K/d²

Condition 1;

K = 155 × 3960²

Distance of space station from the center of the earth;d' = (3960+ 240)+4200 miles

Condition 2;

W' = K/d'²

W × d² = W' × d'²

155 × (3960)²=W'× (4200)²

W'=146.1 pounds

The approximate weight of the astronaut when she is standing on a space station will be 146.1 pounds.

Hence option C is correct.
