The turn ratio of the transformer is 40.
<h3 />
<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.

Answer:
i can't sorry
Explanation:
I didn't really pay attention in that class
The average velocity is -4.17 m/s
Explanation:
The average velocity of a body is given by:
where
d is the displacement of the body
t is the time elapsed
For the student in this problem, we have:
Initial position: 
Final position: 
So the displacement is
The time elapsed is
t = 60 s
Therefore, the average velocity is
Where the negative sign means the student is moving towards the origin.

Answer:
133.8 N
Explanation:
Recall that the acceleration of gravity in Neptune is estimated as 11.15 m/s^2
Therefore, the weight of the dog on this planet would be:
Weight = mass x acceleration of gravity = 12 kg x 11.15 m/s^2 = 133.8 N
