(17%) Problem 1: An object oscillates with an angular frequency o = 3 rad/s. At 1-0, the object is at xo = 3.5 cm. It is moving with velocity vx0= 2 cm/s in the positive x-direction. The position of the object can be described through the equation x() = A cos(o1+). 33% Part (a) What is the the phase constant of the oscillation in radians? (Caution: If you are using the trig functions in the palette below, be careful to...

A conducting wire formed in the shape of a right triangle with base b = 38 cm and height h = 65 cm and having resistance R = 1.1 Ω, rotates uniformly around the y-axis in the direction indicated by the arrow (clockwise as viewed from above (loooking down in the negative y-direction)). The triangle makes one complete rotaion in time t = T = 1.8 seconds. A constant magnetic field B = 1.1 T pointing in the positive z-direction...
One of the most important classes of time dependent signals are periodic signals. Periodic signals satisfy tho following signal equations, x(t) X(t) x(t+nt) for n 2,3. The periodic signals to be observed in this laboratory assignment are shown below. In all the examples A represents the amplitude of the signal and may be given as the measurement from 0 to the peak value A, Apk or can be given as the measurement between A and -A which defines a peak-to-peak...
