The roughness of the surface, the mass of the object, and the area of contact.
Answer: 10^-3 V^2/Hz
Explanation:
1 Hz:
Su(f) = No * |H(f)|^2
= 10^-3 * 1/(1+(2*pi*f*R*C)^2)
= 10^-3 V^2/Hz
cant really answer here with text but at the top of the slide it should br positives and towards the bottom its negative.
This is because you go faster at the top of the slide than the bottom and when your at the bottom you slow down
Explanation:
I don't think the coat will make any difference
