Consider the following three signals (1) x(t) = sinc(t); (2) y(t) = et sin(f0t)u(t) (3) z(t) = u(t); where the unit step and the sinc functions are de ned as follows: u(t) = ( 1 t > 0 0 else sinc(x) = sin(x) x : (a) Classify them as power or energy signals (b) Compute their energy or power (c) Compute the autocorrelation function of x(t)

Jasmine is diving off a 3-meter springboard. her height in meters above the water when she is x meters horizontally from the end of the board is approximated by the equation h=-x^2+3x+3. what is the maximum height jasmine will reach on her dive?

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

He viscosities of several liquids are being compared. all the liquids are poured down a slope with equal path lengths. the liquid with the highest viscosity will
