Asample of 0.800 kg of water is held at a temp of 100°c. how much energy must be added to completely turn the liquid water to water vapor? ( the latent heat of vaporization for water is 2260 kj/kg; the latent heat of fusion for water is 333 kj/kg.) a. 1810 kjb. 266 kjc. 256 kjd. 2830 kj

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 .
