I would be grateful for some help/tips/with this question. Let (V,<,>) be a complex inner product space with an orthonormal basis {v1,v2,...vn}. Let L:V------>V be a linear operator. Explain what is meant by saying that L is self-adjoint. Let A=a_ij be the matrix representing L with respect...

Hi again, I've just started AS physics and am not familiar with this stuff much. I don't know where does my teacher get these question from when they are not in the book. (a) k=50 N/m, x=0.08 m using F=kx, F=50x0.08=4N Now using F=ma to acceleration a=F/m, 4/0.18=22.22...N/mkg...

hello, Thanks for the quick reply. Mass of trolley: 180g or 0.18 kg compression: 8cm or 0.08m Using F=extentionxconstant to find Force 50/0.08=625N Now using F=ma to find acceleration 625/0.18=3472.22...Am i correct? (b) using W=1/2kx^2 25x0.64=16J...

Hello, I found one of my this homework question difficult and was wondering if anyone could please help me. A 180g trolley is placed on frictionless air track. One end of the trolley is attached to a spring of spring constant 50 N/m. The trolley is pushed against a fixed support so that...

Hello, out of 23 homework questions i found this difficult. can anyone help please. Q22. Two coils A and B are made around two tubes. Each has teh same number of turns of wire and is the same size. A soft iron bar is placed inside each tube. (a)The same currect is passed through A and...
