The oscillating current in an electrical circuit is as follows, where \( I \) is measured in amperes and \( t \) is measured in seconds. \[ I=4 \sin (120 \pi t)+\cos (60 \pi t) \] Find the average current for each time interval. (Round your answers to three decimal places.) (a) \( 0 \leq t \leq \frac{1}{50} \) amps (b) \( 0 \leq t \leq \frac{1}{240} \) amps (c) \( 0 \leq t \leq \frac{1}{30} \) amps
