The radius of Earth is 6.37 x 10° m. The average Earth-Sun distance is 1 496 x 1011 m. How many Earths would fit between Earth and the Sun if they are separated by their average distance? Use an order-of-magnitude calculation to estimate this
number. Then, determine an exact answer and express it in scientific notation with the correct number of significant digits.

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
