<h3>What is a transformer?</h3>
A transformer is an electrical device that is used to step up or step down voltage.
The formula for calculating the turns ratio of a transformer is given below.
<h3> Formula</h3>
- a = V/v.......... Equation 1
Where:
- V = Primary voltage
- v = Secondary voltage
- a = Turns ratio of the transformer
From the question,
Given:
Substitute the values above into equation 1
Hence, The turn ratio of the transformer is 40.

The elapsed time when the particle returns to the origin is determined from the ratio of initial velocity and acceleration of the particle.
<h3>Time of motion of the particle</h3>
The time of motion of the particle is calculated by applying Newton's second law of motion.
F = ma
F = m(v)/t
where;
- t is time of motion of the particle
- m is mass of the particle
- v is velocity of the particle
a = v - u/t
v = u + at
when the particle returns to the origin, direction of u, = negative.
final velocity = 0
0 = -u + at
at = u
t = u/a

Answer:
The change of the volume of the device during this cooling is 
Explanation:
Given that,
Mass of oxygen = 10 g
Pressure = 20 kPa
Initial temperature = 110°C
Final temperature = 0°C
We need to calculate the change of the volume of the device during this cooling
Using formula of change volume
Put the value into the formula
Hence, The change of the volume of the device during this cooling is
