How do solids, liquids, and gases differ?

Physics

wariber [46]3 years ago

Solids, liquids and gases :
In solids the particles like molecules of the substance - are very close to each other. They cannot move far from their positions.  In liquids they are separated by some more distance. SO molecules are freely moving inside liquid.  But in gases the molecules are free to move with in the volume.
Gaseous molecules have higher speeds.

Solids have good conductivity of electricity. Some liquids are also conductive. gases may be less conductive. 

Gases have no shape of their own.  Liquids do not have a shape too.  Solids can have some shape and retain their shape.

Gases and Liquids flow. Solids do not flow.

Many gases may be invisible or may be faint in color.  Visibility of liquids and solids is high.

Gases may not taste. they may smell.  Solids and liquids may taste and may or may not smell.

Solids may be transparent to light or may be opaque.  Gases may be highly transparent to light.

Sound travels in solids faster than in gases.

Three children are struggling and pulling on a single toy. Two of the children, Abe and Barry, are EACH (individually) pulling w
3241004551 [841]

Solution :

c). $\vec{F}_A = $ force applied by Abe

   $\vec{F}_B = $ force applied by Barry

   $\vec{F}_E = $ force applied by Eric

   $\vec{F}_R = $ Resultant force

$\vec{F}_A $  in the vector form can be written as :

         $\vec{F}_A = 0 \hat{i} + 60 \hat{j}$

$\vec{F}_B $  in the vector form can be written as :

         $\vec{F}_B = 60 \hat{i} + 0 \hat{j}$

The resultant,

$\vec{F}_R= \vec{F}_A+\vec{F}_B $

     $=(0 \hat i + 60 \hat j)+(60 \hat i + 0\hat j)$

    $=60 \hat i + 60 \hat j$

$|\vec{F}_R| = \sqrt{60^2+60^2}$

        = 84.853 N

d). As the three forces are in equilibrium, therefore,

$|\vec F_E| = |\vec F_R|$

$|\vec F_E| =84.853 \ N$

e). The direction of the force exerted by Eric is exactly opposite to the direction of the resultant force.

The direction of the resultant force is :

$\theta = \tan ^{-1}\left(\frac{F_y}{F_x}\right)$

   $ = \tan ^{-1}\left(\frac{60}{60}\right)$

  = 45°  north east

The direction of the force E is  45° west or  45° south west.

A ball is hung from a rope, making a pendulum. When it is pulled 5° to the side, the restoring force is 1.0 N. What will be the
Trava [24]

Answer:

restoring force is 2 N

Explanation:

given data

angle pulled = 5°

force = 1 N

pulled = 10°

to find out

restoring force

solution

we know here force

force = m×g×sinθ     ..........1

so here θ is very small so sinθ  = θ

1 = mg(5)

mg = 1 /5     ..................2

and

now for 10 degree

we know here θ is small so sinθ  = θ

so from equation 1

force = m×g×sinθ

put equation 2 here

force = 1/5 × 10  

force = 2 N

so restoring force is 2 N
