Two long, straight wires carry currents perpendicular to the xy plane. one carries a current of 50 a and passes through the point x = 5.0 cm on the x axis. the second wire has a current of 80 a and passes through the point y = 4.0 cm on the y axis. what is the magnitude of the resulting magnetic field at the origin? \

Acar is going 5m/s around a bend with a radius of 10m/s why is the accelerant?

There are two-speed cameras, one in an are where the speed limit is 30 km/h and another where the speed limit is 50 km/h. in which will there be a smaller time interval between the photographs? explain your answer.

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
