Water flows with a speed of 2.5 m/s through a section of hose with a cross-sectiona area of 0.0084 m2. Further along the hose the cross-sectional area changes, and the water speed is reduced to 1.1 m/s (a) Is the new cross-sectional area greater than, less than, or equal to 0.0084 m2?
(b) Calculate the new cross-sectional area.

When considering gravity acceleration and the force of acceleration, what must be true? a. the direction of acceleration must be perpendicular to the direction of the force. b. the direction of the force and the direction of acceleration must be the same as each other. c. the direction of the force and the direction of acceleration must be opposite of each other. d. the mass of the body must be the same as the acceleration of the body.

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
