Consider a 3-phase, 4 pole, ac induction motor being driven at 75 hz. initially, the motor is connected to a mechanical load that requires 1,816 w of power. while connected to this load, the motor spins at 1,996 rpm. now a new load is connected that requires 2,334 w of power. what is the new slip on the motor for the new load assuming that the motor is operating in its normal operating range?

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
