The entrance exam

They handed me the ticket to my bright future. All sealed.

I was always told that this is the secret to success. Work hard.

I did.

But the only key to this secret chamber I had, was an allotted admit card number. Two lakh, thirty thousand, six hundred and one. And three hours to crack it.

You may start. Now.

Q1: A triangular wave pulse on a string with a tension F is moving in the positive x direction with a velocity.....

It will take some time. But it will come. I know.

Q2: A source of sonic oscillations S and an observer O start moving along positive x and positive y axis ….

Don’t let it interfere. No distractions. A minute more and it should strike. I know.

Q3: When heat is added to the gas, the temperature increases and the gas expands…..

Just have to remain cool. Calm. Concentrate.

Q4: If the gas is in a rigid container, then the volume remains constant and the pressure increases…..

Breathe in. Breathe out. It will equalize. It should.

Q5: A small block of mass m is placed inside a hollow cone rotating about a vertical axis with angular velocity…..

Hollow? But I remember. I remember cramming it. I must know.

Q6: The arrangement is in a horizontal plane. The particle with mass m is restricted to move in an elliptical orbit with given dimensions…..

No. NO. I know it. It is just a matter of time. It will come out. It has to.

Q7: An unknown resistance is to be determined using known resistances if their corresponding null points are.…..

Hell. Why is there so much friction? It used to flow freely before. God please help.

Q8: The system shown comes to rest. Assume that a can roll slipping along the incline…..

Am I loosing it? I can’t. Didn’t anyone know it’s not mine? It is theirs. Their one and only dream. What answer will I give them?

Q9: A wire when stretched by a weight of a solid gives a frequency f. .The fundamental tone oscillations are excited with angular frequency…..

What?

Q10: A uniform rope of mass m and length l is whirled in a horizontal circle about one of its ends…..

The only answer.

Q11: A wave of frequency n propagates through the rope; find the phase difference between the top and the bottom of the rope.

As the rope of length l and mass m hangs from the ceiling.

Yes exactly, in some moments I can bruit about that I agree with you, but you may be making allowance for other options.
