The ratio of the turns to the voltage should be equal
i.e: 200/120 = t/12
so the secondary coil should have 20 turns

topjm [15]

Answer:

34.64 cm

Explanation:

Given that:

The depth of the hole h = 10 cm

height of the water holding in the tank H = 40 cm

For a stream of flowing water, the distance (x) at which the stream strikes the floor can be  computed by using the formula;

x = 2 \sqrt{h(H-h)}

x = 2 \sqrt{10(40-10)}

x = 2 \sqrt{10(30)}

x = 2 \sqrt{300}

x = 2 \times 17.32

x = 34.64 cm
