A \(1.0-\mathrm{kg}\) brick is placed on a spring scale inside the space shuttle orbiting Earth at \(300 \mathrm{~km}\) altitude.

(a) What is the magnitude of the force exerted by Earth on the brick?

(b) What is the magnitude of the force exerted by the brick on the spring scale?

(c) Does the spring scale measure the pull of gravity on the brick?

(d) Why is your answer different from your answer to Checkpoint 13.8, part \(d\) ?
