I’m not really sure I’m sorry
The maximum height reached is 45.92 m
Hope this helps, if you need clarification i got you
Answer:
Emf induced i equal to 329.4 volt
Explanation:
Note : Here i think we have to find emf induced in the coil
Number of turns in the coil N= 180
Sides of square d = 30 cm = 0.3 m
So area of the square 
Magnetic field is changes from 0 to 1.22 T
Therefore 
Time interval in changing the magnetic field dt = 0.06 sec
Induced emf is given by


<h3><u>Answer;</u></h3>
= 21600 Joules or 21.6 Kilo joules
<h3><u>Explanation;</u></h3>
Electrical energy is given by the formula = VIt ;
where V is the voltage in volts, I is the current in Amperes, and t is time in seconds.
Voltage = 120 volts
Current = 3 amperes
Time = 60 seconds or 1 minute
Therefore;
Electrical energy = 120 × 3 × 60
<u> = 21600 Joules or 21.6 Kilo joules</u>
