Flux through a Cube (Eigure 1) A cube has one corner at the origin and the opposite corner at the point (L, L, L). The sides of the cube are parallel to the coordinate planes
Consider the three circuits shown above. All the resistors and all the batteries are identical. Which of the statements are true and which ones are false?
1)The power dissipated in circuit A is twice the power dissipated in circuit B.
2) The current through a resistor is the same in circuits A and C.
3) The current through a resistor is the same in circuits A and B.
4) The voltage across a single resistor in circuit C is twice the voltage across a single resistor in circuit B.
5) The total power dissipated in circuit C is twice the total power dissipated in circuit B.
An oil pump is drawing 44 kW of electric power while pumping oil with ρ= 860 kg/m^3 at a rate of 0.1 m^3/s. The inlet and outlet diameters of the piper are 8 cm and 12 cm, respectively. If the pressure rise of oil in the pump is measured to be 500 kPa and the motor efficiency is 90 percent, determine the mechanical efficiency of the pump.
