A 3 m high large tank is initially filled completely with water. The tank water surface is open to the atmosphere, and a sharp edged 10 cm diameter orifice at the bottom drains to the atmosphere through a horizontal 80 m long pipe. If the total irreversible head loss of the system is determined to be 1.5 m, determine the velocity of the water as it exits the pipe. Take the density of water as 1000 kg/m3.

Write a hypothesis about the effect of increasing resistance on the current in the circuit. use theformat and be sure to answer the lesson question. “how do changes in voltage or resistance affect current in an electric circuit? ”

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
