The turns ratio is equal to the voltage ratio. Let n1 and n2 be the primary and secondary turns. Then
5850V/120V=n1/n2
48.75=2680/n2
n2=2680/48.75
n2=55
Answer: Velocity can best be described as, the speed in a given direction.
Explanation: To find the answer, we need to know more about the Velocity of a body.
<h3>What is Velocity of a body?</h3>
- Velocity is the rate of change of displacement.
- It's a vector quantity and is measured in m/s.
- It can be positive, negative or zero.
- A body is said to be in uniform motion, then its velocity remains constant.
- Change in velocity can be a change in speed.
- The magnitude of velocity is less than or equal to speed.
Thus, we can conclude that, the option C is best describing velocity.

So Neon ( Ne) is the correct answer.
The distance from the horizontal top surface of the cube to the water level is "6.282 cm".
<h3>What is Archimedes' principle?</h3>
According to Archimedes' principle, the weight of the fluid that the body displaces is equal to the upward buoyant force that is applied to a body submerged in a fluid, whether fully or partially. The Archimedes' principle is a fundamental physical law in fluid mechanics. It was created by Syracuse's Archimedes.
According to Archimedes' principle, a body submerged in a fluid experiences an upward force proportional to the weight of the fluid that has been displaced. One of the prerequisites for equilibrium is this. We believe that the buoyancy force, also known as the centre of buoyancy, is situated in the middle of the submerged hull.
From Archimedes' principle, we get



=11.72cm
So,
The distance from horizontal top to the water level will be:
=18-11.72
=6.282cm
