Does anyone know, exactly what in an amp causes distortion? And what does the gain button change, causing more or less distortion?
Also does anyone know, why the graph of gain vs distortion is a logarithmic curve?

A boy whose mass is 35kg and a girl at 25kg face each other initially at rest on frictionless rollar skates. The boy pushes the girl, who moves away at a speed of 1.5 m/s. Whats the boys speed?

I used the elastic collison equation:
V1f = (35-25/35+25)0 + (2(25)/35+25)1.5
V1i = (50/60)1.5
V1i = (.83)1.5
V1i = 1.25 m/s



am I close??

my dads colleague said that he can generate electricity!!!...he said that if he touches a metal surface after walking for a long time...he gets an electric shock!!..and if he touches someone else...they too get an electric shock..once...he was walkin in a supermarket with his wife...pushin a trolly..suddenly his hand hit the metal side of the trolly and he got an electric shock...he asked his wife if she wanted an electric shock...she thought that he was joking...so she said yea...he asked her to touch him and touch the metal part of the trolly..when she did...sparks came up...another time...when this man was walking....he hit upon some metal surface and realised that hes having the power again..so he went and touched a colleagues face...and it that spot got burnt!!...he says that it is basic physics...something to do with the iron content in his body...my mom feels that he has some health problem...can someone tell me what exactly is happening??..

Ok, so I might be using stereotypes but hey....

so I was just looking out of my office window, and i saw a rather large man walking down the street. And i wondered, do his shoes wear out quicker cos he is larger, and hence more weight. But then i thought he probably doesnt walk as far as someone of less weight!?!

which got me thinking, in general, people with larger feet, are taller, and hence heavier. Is there some correlation between the size of shoe and how quick they wear out.

there seems like lots of variables tho. are people with larger feet more likely to scuff (drag) their feet? how much does the size of the shoe spreading out the weight compensate for the extra weight?

What do you think!?!

TOTAL 3 qns:
A child slides across a floor in a pair of rubber-soled shoes. The friction force acting on each foot is 22 N, the footprint area of each foot is 16 cm2, and the thickness of the soles is 5.0 mm. Find the horizontal distance traveled by the sheared face of the sole. The shear modulus of the rubber is 3.0 106 Pa.

Another qn:
9.16 A 10.0 kg block of metal is suspended from a scale and immersed in water as in Figure P9.30. The dimensions of the block are 12.0 cm 10.5 cm 10.5 cm. The 12.0 cm dimension is vertical, and the top of the block is 5.00 cm below the surface of the water

a) What are the forces exerted by the water on the top and bottom of the block? (Do not ignore the effect of the air above the water. Take P0 = 1.0130 105 N/m2.) Ftop N
Fbottom N
(b) What is the reading of the spring scale?
N
(c) Show that the buoyant force equals the difference between the forces at the top and bottom of the block.
