Which best explains why astronauts appear weightless when they are in a space shuttle orbiting earth? they are falling toward earth at the same rate as the space shuttle. they are falling toward earth at a faster rate than the space shuttle. they are too far from earth to experience gravity. they are too far from earth to experience air resistance.

The astronauts appear weightless when they are in a space shuttle as they are falling towards Earth at the same rate as the space shuttle. It is the speed which is responsible for the reason why astronauts appear weightless. They do not fall towards Earth due to its high orbital velocity, they accelerates towards Earth and the Earth curves away beneath them and they do not come closer to the Earth.Since, the astronauts have the same acceleration as that of the space station, so they are weightless.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
