Yes, the force of friction acts tangentially to the surface of the rolling body at the point of its contact with the surface (point A in the diagram above).

The force of friction mainly depends upon the area of the body in contact with the surface. In case of a pure rolling body the area under contact with the surface is very negligible, therefore the frictional force acts tangentially.

The only reason why we use wheels in cars for fast transportation.

Cool game dude !! how do you do all these things?? Even I wanna learn!! Could have made your pictures more better!!

Congrats !!!

Congrats Dude!!

There is a imp relation between R1 and R2 (complimentary angles wala), you will find that R1 = R2

As,

R1 = U² Sin2(40) /g

R2 = u² Sin2(50) /g

As, Sin2(50) = Sin2(40)....... {Bcoz Sin(90+10) = Sin (90-10)}

We have R1 = R2 (provided that U = u)

Look at the diagram if you have any confusion!

Re:projectile motion

Tarin & Lokesh lie amongst the most funniest, cool & idiotic personalities on Go IIT!

Check out this forum .. Probably the most funniest on Go IIT!

All Cheers to Tarin and Lokesh ..

How many of them agree with my first point about Tarin and Lokesh???

Give your compliments and comments... he he

Formula:

(Surface tension) S = F / L

Where,

F >>> It is the common magnitude of all the forces across PQ.

L >>> Length of PQ

What else do you want regarding surface tension???

Rates wanted...Salutes are must for all the efforts taken!!!

Details:

Consider the diagram above. The line PQ divides the liquid into two. It is found that both the surfaces (on either side of line PQ) pull each other with a force that is proportional to length PQ. Therefore the surface of the liquid behaves like a rubber sheet stretched from all the sides. So the liquid contracts and tries to reduce its surface area.

Re:Surface Tension

Cause:

Asymmetric forces between molecules of the liquid as shown in the fig above...

Re:Surface Tension

Surface Tension:

Definition:

You can define surface tension as the tendency of a liquid to decrease its surface area.

Got the answer from Himanshus post,

Let a and b be the two positive nos,

Given,

x = (a + b) / 2 = AM ..(i)

a, y, z, b are in G.P

To find: (y³ + z³) / xyz

Let the common ratio be r,

Therefore,

y = ar;

z = ar²;

b = ar³;

Therefore r³ = b/a ..(ii)

y³ + z³ = a³r³ + a³r⁶ ..(iii)

Now, Substitute (ii) in (iii), we have,

y³ + z³ = a²b + ab² = ab (a + b) ..(iv)

yz = (ar)(ar²) = a²r³ = ab (because b = ar³) ..(v)

Substituting the values of equation (i), (iv) and (v) in

(y³ + z³) / xyz

We have,

(y³ + z³) / xyz = ab (a + b) / ab (a + b) / 2

= 2

Is the answer right???

How do you do this ... plz get me the software...plz

Cool Theme,

Nice job Himanshu. Well, I couldnt prepare a separate download link, but I have found one ?

Download via this link if rapid share doset work

Dude, send me the ring tone at indzee@gmail.com, I will try to make and upload a download link over here. It will make your work easy.
