A particle is moving in a circular path of radius r . The displacement after half a circle would be

Answers

Answer 1
Answer:

Answer:

2r

Explanation:

As we know that

The displacement is the total distance measured between the initial or start and final or destination point

If particle cover half path of the circle, the displacement can easily find out by considering the distance between the start and destination point

We attached the diagram for better understanding

As per the diagram.

The displacement after half-circle is

AB = OA + OB

= r + r

= 2r

A lens of focal length 15.0 cm is held 10.0 cm from a page (the object ). Find the magnification .

Answers

Answer:

Magnification, m = 3

Explanation:

It is given that,

Focal length of the lens, f = 15 cm

Object distance, u = -10 cm

Lens formula :

(1)/(v)-(1)/(u)=(1)/(f)

v is image distance

(1)/(v)=(1)/(f)+(1)/(u)\n\n(1)/(v)=(1)/(15)+(1)/((-10))\n\nv=-30\ cm

Magnification,

m=(v)/(u)\n\nm=(-30)/(10)\n\nm=3

So, the magnification of the lens is 3.

Answer:

3.00 - Magnification.

Now this is REALLY helpful ( I hope)

Image distance :

-30.0

It is CORRECT FOR ACELLUS!

I wish you luck!

Interactions between biosphere and hydrosphere

Answers

The Hydrosphere is all the water on Earth, and the Biosphere is all the living organisms on Earth. So, if you are looking for an interaction between the two spheres, it would be an interaction between water and organisms. When it rains, the plants and animals receive the rain. Fish, algae, and other aquatic animals live in the Hydrosphere-the ocean.
