a micrometer screw gauge has a -0.03mm error. state the reading that is observed on the instrument when used to measure the diameter of a wire whose actual diameter is 0.38.

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 .
