A lamp is connected to the power supply. The lamp requires an input potential difference of 5.0V

The alternator generates a potential difference of 1.5V

The primary coil of the transformer has 150 turns.

Calculate the number of turns needed on the secondary coil

Number of turns on the secondary coil = ?

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
