The distance of the nearest star from the Sun is approx 4 × 1016 m. Our galaxy otherwise known as the Road

of Milk has a disk approximately in diameter

1021 m and thickness approximately 1019 m. Find the order of

the size of the number of stars in the Milky Way.

Suppose the distance between Dill and our neighbor

the closest is typical.

An astronaut floating in space is trying to use her jetpack to get back to her space station, but she is being pulled away by a nearby planet, as shown in the image below. her jetpack provides a constant thrust of 310 n. if she angles her jetpack in such a way that it cancels out the vertical force due to the planet's gravity, what is her net horizontal force? thaud 487 o a. 54.8 n toward the space station o b. 212.9 n toward the space station o c. 185.2 n toward the space station o d 956 n toward the space station
