When two charge producers with different surface materials are rubbed together to create a charge imbalance, how will the electric charge on one of the producers compare to the electric charge on the other? When two different materials are rubbed together to create an imbalance of charges, the charge of both producers cancel out making zero charge. When two different materials are rubbed together to create an imbalance of charges, the charge on one of the producers will be the same as the charge on the other. When two different materials are rubbed together to create an imbalance of charges, the charge on one of the producers will be the opposite of the charge on the other.

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy. work depends on the square of the change in potential energy. work is equal to the negative of the change in kinetic energy. work is equal to the square of the change in kinetic energy
