- Figure P7.45 shows a picture of American astronaut Clay Anderson experiencing weightlessness on board the International Space Station. a. Most people have the misconception that a person in a spacecraft is weightless because he or she is no longer affected by gravity. Show that this premise cannot be true by computing the gravitational field of the Earth at an altitude of 200 km the typical altitude of a spacecraft in orbit. Compare this result with the gravitational field on the surface of the Earth. b. Why would astronauts in orbit experience weightlessness even if they are experiencing a gravitational field (and therefore a gravitational force)?arrow_forwardA 0.400-kg pendulum bob passes through the lowest part of its path at a speed of 3.00 m/s.

- At small scales, viscous drag becomes very important. To a paramecium (shown), a singlecelled animal that can propel itself through water with fine hairs on its body, swimming through water feels like swimming through honey would to you.

The drag force decreases by a factor of 2.B. The drag force is unaffected.C. The drag force increases by a factor of 2.D. The drag force increases by a factor of 4.arrow_forward(a) What will an object weigh on the Moon’s surface if it weighs 100 N on Earth’s surface?
