A500-turn solenoid, 25 cm long, has a diameter of 2.5 cm. a 10-turn coil is wound tightly around the center of the solenoid. if the current in the solenoid increases uniformly from 0 to 5.0 a in 0.60 s, what will be the induced emf in the short coil during this time?

By what factor does the drag force on a car increase as it goes from 65 to 110 km/h?

Which describes increasing the efficiency of energy resource

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
