You are designing a manned submersible to withstand the pressure of seawater at the bottom of the mariana trench, which is one of the deepest parts of the earth’s oceans. the bottom of the trench is at a depth of 10,900 m. part a what is the gauge pressure at this depth? (you can ignore the small changes in the density of the water with depth.)part b what is the inward force on a circular glass window 6.0 cm in diameter due to the water outside? part c if the internal pressure is 1 atm, what outward force does this produce on the window? (you may ignore the small variation in pressure over the surface of the window.)

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction 

Is there any opitions? if you have the periodic table, the noble gases are 8a family, the halogen are the 7a family, and the nonmetal are  carbon, nitrogen, phosphorus, oxygen, sulfur, selenium, fluorine, chlorine, bromine, iodine and astatine.

  the answer is don't know.
