If you float a piece of wood in a container half-full of water that rests on a weighing scale, the weight reading on the scale will increase.
<h3>What is Buoyancy?</h3>
Buoyancy is the force through your fluids or total or submerged bodies. Also known as Archimedes' theorem. The fluid of the direction on the body produces a resultant force but with the direction of the weight, with the opposite direction, upwards.
All material submerged in a liquid under the action of buoyancy, for this reason we have that the value on the scale will be increased with a system of a wood floating in water.

To solve the problem it is necessary to apply the concepts related to the voltage in a coil, through the percentage relationship that exists between the voltage and the number of turns it has.
So things our data are given by
PART A) Since it is a system in equilibrium the relationship between the two transformers would be given by
So the voltage for transformer 2 would be given by,
PART B) To express the number value we proceed to replace with the previously given values, that is to say
Use force (thrust) equals mass times acceleration.
