Ascientific blank must be testable and capable of being proven false?

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 .

Awave with a frequency of 500 hz is traveling at a speed of 100 m/s.what is the wavelength?
