Answer: the difference in the number of turns in each coil

Explanation:

A transformer is a device which is used transfer electrical energy from one circuit to another. It uses coils - primary and secondary having different turns. The current passes through the primary coil which induces emf in the secondary coil. The increase in potential depends on the number of turns in the coil.

\frac{V_{out}}{V_{in}}=\frac{N_s}{N_p}

where V is the voltage and N is the number of turns.

Which of these is most likely to lead directly to a black market?
Nookie1986 [14]
 I would say it's rationing: if people are only allowed a certain number of something (let's say: bottles of cooking oil), then the people who are entitled to is (as all are) but don't need is as much are likely to try to make profit by trying to sell it on a black market.

The ball in front of you is going to drop one meter. how long will it take to fall?
Pavlova-9 [17]

The ball will take 0.45 seconds to reach the ground

<h3>How will we solve this question?</h3>

We will use Newton’s laws of motion, so

H= (1/2)gt^2 taking height= 1m

1= (1/2) x 9.8 x t^2

t=\sqrt{10/49} = 0.45 seconds

<h3>What are the three laws of motion given by Newton?</h3>

The 3 laws of motion given by Newton are as follows:

1) Unless an unbalanced force acts upon it, an item at rest remains at rest, and an object in motion continues to move in a straight line at a constant pace.

2) An object's acceleration is influenced by its mass and the force being applied.

3) Whenever one thing applies force to another, the second object applies the opposing, equal force to the first.

Find the velocity. 10 points. Will give brainliest!
BARSIC [14]

Answer:

6.060606...

Explanation:

To figure out velocity, you divide the distance by the time it takes to travel that same distance, then you add your direction to it. So the distance would be 1000m and the time would be 2 minutes and 45 seconds and if you convert the minutes into fractions you would get 165 seconds than you would divide 1000m by 165 seconds and you would get 6.060606... seconds as her average velocity

A myopic person has a far point of 1.000m. If she wears her eyeglass 2.0cm in fromt of here eyes, what is the power of her eye g
Iteru [2.4K]

Answer:

51 dioptre

Explanation:

u = Object distance =  2 cm

v = Image distance = 1 m

f = Focal length

Lens Equation

\frac{1}{f}=\frac{1}{u}+\frac{1}{v}\\\Rightarrow \frac{1}{f}=\frac{1}{0.02}+\frac{1}{1}\\\Rightarrow \frac{1}{f}=\frac{1.02}{0.02}\\\Rightarrow \frac{1}{f}=51\\\Rightarrow f=\frac{1}{51}

Power of lens

P=\frac{1}{f}\\\Rightarrow P=\frac{1}{\frac{1}{51}}\\\Rightarrow P=51\ D

Power of the eye lens is 51 dioptre.
