Thanks for your reply StatusX. I really appreciate it. Saksham

I was asked to integrate( exp(-x) cos(x)) with respect to x with the limits x=0 and x= infinity. I calculated the indefinite integral to be 0.5 exp(-x) [sin(x)-cos(x)]. I was stuck in the part where we apply limit x approaches infinity of sin(x) and cos x. Please help me out. Saksham

Under what circumstances are the traverse speed and speed of propagation equal?

Help Needed! Waves, Urgent! ******Mathematical description of a wave:****** A transverse wave on a string can be described by: Y(x,t)= A cos [k(x-vt)] a) Find the maximum transverse speed vy of a particle of the string. Under that circumstances is it equal to the propagation speed of the...

Help me people! I have to meet the deadline tomorrow.

Thanks Nylex! Could anyone solve the other one for me, please! I need it desperately.

**** Intensity and spherical waves***** Sound waves are spreading out equally in all directions from a points source. You measure an intensity of 0.026 W/m2 at a distance of 4.3 m from the source. a) What is the intensity in a distance of 3.1 m from the source? b) How much sound energy does...

What is the Moment of inertia of a uniform cone about the axis joining the center of its base and its apex. Iis it 3/10*(M*R^2) where M is the mass of the cone and R the radius of the base of the cone?

Thanks ehild. That was what I wanted but I think we get the result that they both reach the bottom at the same time. Thanks to all the people who replied. And, I did not have that question in the midterm, had I got that then I would have got that correct. Thanks once again. Cheers, Saksham

This is my Physics assignment. I am sure that there should be some theory behind it. As you can see that it is either true or false. We should consider rotational and translational kinetic energy. But who reaches the bottom first?

Two persons of different mass roll down the same hill from the same starting point on identical bicycles. Neglect friction and air resistance and assume that the tires roll without slipping. Which person will reach the bottom first? Prove. I have mid term tomorrow. Saksham

What if the person uses his muscles too, not only his weight?

A small thought- Undergrad at Bremen The law of conservation of energy as you mentioned will hold only when you have a free falling body when it starts to fall with PE=mgh and KE=0 and when it just reaches the ground, it has PE=0 and KE=0.5*m*(v)^2. When you are climbing down the stairs as...

Thanks. Thank you very much schutte, I am really grateful to you for saving three marks for me in my mid term. Cheers, Saksham

Hello, I am a Freshman from International University Bremen. I would like to request you to help me out with a small question. I have a system of springs. Two springs with spring constants k1 and k2. I attach them to the opposite ends of a mass m1 and then attach the other ends of the springs...
