please solve part A and part B

Electricity is distributed from electrical substations to neighborhoods at 14000 V. This is a 60 Hz oscillating (AC) voltage. Neighborhood transformers, seen on utility poles, step this voltage down to the 120 V that is delivered to your house. Part A How many turns does the primary coil on the transformer have if the secondary coil has 100 turns? Express your answer using two significant figures. View Available Hint(s) AED ? nprim = turns Submit Part B No energy is lost in an ideal transformer, so the output power Pout from the secondary coil equals the input power Pin to the primary coil. Suppose a neighborhood transformer delivers 290 A at 120 V. What is the current in the 14000 V line from the substation? Express your answer using two significant figures and include the appropriate units
