Aroom in the lower level of a cruise ship has a 30-cmdiameter circular window. If the
midpoint of the window is 5 m below the water surface, determine the hydrostatic force
acting on the window, and the pressure center. Take the specific gravity of seawater to
be 1.025

Carbon-14 is a radioactive element that undergoes beta decay. which force is responsible for allowing carbon-14 to become stable? electromagnetic gravitational weak nuclear strong nuclear

3. which is not a primary color of light? blue red green yellow

Atrain is traveling at 30.0 m/s relative to the ground in still air. the frequency of the note emitted by the train whistle is 262 hz. the speed of sound in air should be taken as 344 m/s. what frequency (f approach) is heard by a passenger on a train moving at a speed of 18.0 m/s relative to the ground in a direction opposite to the first train and approaching it? what frequency (f recede) is heard by a passenger on a train moving at a speed of 18.0 m/s relative to the ground in a direction opposite to the first train and receding from it?
