An Object is located 16 cm in front of a converging lens with focal length 12 cm. To the right of the converging lens, separated

ExtremeBDS [4]

Answer:

image is located at 22.5cm to the left of diverging lens.

Explanation:

In this question we have given,

object distance from converging lens,u=-16cm

focal length of converging lens, $f_{c}=12cm$

focal length of diverging lens, $f_{d}=-10cm$

distance between converging and diverging lens=20cm

we have to find location of final image,v=?

Here we will first find the location of image formed by converging lens

we know that u, v and $f_{c}$ are related by following formula

$\frac{1}{f_{c}} =\frac{1}{v}- \frac{1}{u}$ .............(1)

put values of $f_{c}$ and u in equation (1)

we got,

$\frac{1}{12} =\frac{1}{v}- \frac{1}{-16}$

$\frac{1}{12}-\frac{1}{16} =\frac{1}{v}$

$\frac{16-12}{16\times 12} =\frac{1}{v}$

or

$v=\frac{16\times 12}{16-12}\\ v=48cm$

The image is located 48 cm to the right of the converging lens. This image is real and inverted.

This image will object for the diverging lens which is now located (48-20=18) cm at the right hand side of diverging lens

it means,

u=18cm

we know that u, v and $f_{d}$ are related by following formula

$\frac{1}{f_{d}} =\frac{1}{v}- \frac{1}{u}$ .............(2)

put values of $f_{d}$ and u in equation (2)

$\frac{1}{-10} =\frac{1}{v}- \frac{1}{18}$

$\frac{1}{-10}+\frac{1}{18} =\frac{1}{v}$

$\frac{-18+10}{10\times 18} =\frac{1}{v}$

or

$v=\frac{10\times 18}{10-18}\\ v=-22.5cm$

It means image is located at 22.5cm to the left of diverging lens.

Suppose a candle is burning, and wind is blowing on one side of the flame. Which principle explains why the flame bends toward t

Mekhanik [1.2K]

When a candle is burning and wind is blowing it on one side of the flame, which causes the flame to bend towards the wind is an example of Bernoulli’s principle. The principle explain that the higher the speed, the lower the pressure becomes. When you blow against one side of the flame, you are creating an area of low pressure. The relatively high-pressure air on the other side of the candle will rush over to fill the area of low pressure that causes the flame to be pushed in the direction of the blowing.

If I exert a 203 N force on a 58 kg box, what will the acceleration of the box be?

Anit [1.1K]

Answer:

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

$a = \frac{f}{m} \\$

m is the mass

f is the force

From the question we have

$a = \frac{203}{58} = \frac{7}{2} \\$

We have the final answer as

Hope this helps you

How does visible Light travel through outer space?

Dima020 [189]

By the electromagnetic "vibrations" that make up light. Said EM vibrations are an electric field and a magnetic field at right angles to each other and to the direction of propagation/travel. Light travels by the same "mechanism" that X rays travel, radio waves travel and anything else in the vast electromagnetic spectrum. Probably how I'm able to type these words on a computer key board and have them transmitted "Wi Fi" like, to you, the hapless recipient. You're a Cheetah ??? That means you can run like the wind ????
