Consider a weakly-damped, but undriven oscillator. the general equation of motion is where the damping force fdamp = -bv so β = -b/2m and ω0 is the natural frequency. (a) use this to sketch the state-space orbit, showing the movement of (x, x’) for 0< t< 10 with the parameters x(0) = π/4, x’(0) = 0, ω0 =2π, and β=0.5. (b) what type of attractor does this system have? what is it? explain it, both with reference to your sketch and in terms of energy conservation.

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.

When using the scientist method, which step comes last?

Asign is hung between two cables as illustrated below. if the sign weighs 350 n, what is the tension (in n) in each cable?
