because now you no need to worry about it and you can just answer in your paper
D. The maximum electromotive force induced in the coil is determined as 3,200 V.
<h3>
Maximum electromotive force induced in the coil</h3>
emf(max) = NAB/t
where;
- N is number of turns
- B is magnetic field
- A is area of the coil
- t is time
Substitute the given parameters and solve for emf
emf(max) = (150 x 0.042 x 0.86) / (1.7 x 10⁻³)
emf(max) = 3,187.1 V
emf(max) ≈ 3,200 V
Thus, the maximum electromotive force induced in the coil is determined as 3,200 V.

Answer:
Kindly check explanation
Explanation:
Given the following :
Distance between Ranjan and Gomez house = 9km
Start time = 6'o clock
Time he arrived at Gomes house = 7'o clock
Time used for chatting during this period = 5 minutes
Distance covered in 40minutes = 6km
Time spend for second part of the journey = (60 - (40 + 5))minutes = 15 minutes = 15/60 = 0.25 hoir
Distance covered during second part of journey = 9 - 6 = 3 km
Speed = distance / time
Speed = 3km / 0.25 hr = 12km/hr
Average speed for entire journey :
First part :
Speed = distance / time
Time = 40 minutes = (40/60) = 0.667 hour
Speed = 6km / 0.667 hour = 9km / hr
Average speed :
(First part + second part) / 2
(9km/hr + 12km/hr) / 2 = 21km/hr / 2 = 10.5 km/hr
= 10.5km/hr
Answer: [D]: China .
