At a soft drink bottling plant, a horizontal section of pipe carrying citric acid in liquid form goes from a cross-sectional area of 8.00 cm2, fluid flow speed of 310 cm/s, and pressure of 1.40 105 pa to a section of pipe with a cross-sectional area of 4.00 cm2. the density of the citric acid is 1660 kg/m3. for the section of smaller pipe, determine the liquid flow speed and the liquid pressure

(a) the liquid flow speed m/s

(b) the liquid pressure pa

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?

Aball is thrown vertically upwards from the top of a tower with a speed of 100m/s. it strikes the pound near the base of the tower after 25sec . the height of the tower is

Irrigation channels that require regular flow monitoring are often equipped with electromagnetic flowmeters in which the magnetic field is produced by horizontal coils embedded in the bottom of the channel. a particular coil has 100 turns and a diameter of 6.0 m. when it's time for a measurement, a 4.5 a current is turned on. the large diameter of the coil means that the field in the water flowing directly above the center of the coil is approximately equal to the field in the center of the coil. the field is directed downward and the water is flowing east. the water is flowing above the center of the coil at 1.5 m/s . what is the magnitude of the field at the center of the coil? what is the direction of the force on a positive ion in the water above the center of the coil? what is the magnitude of the force on an ion with a charge +e?
