A) calculate the absolute pressure at an ocean depth of 1150 m. assume the density of sea water is 1023 kg/m^3 and that the air above exerts a pressure of 101.3 kpa. b) at this depth, what force must the frame around a circular submarine porthole having a diameter of 31.0 cm exert to counterbalance the force exerted by the water?

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.

Acar of mass 800kg is moving at a speed of 2.2m/s.
