please. write with clear solution

Assume that a shaker is excited to vibrate using the following signal, z(t)=5sin(9000t)+2sin(18000t) where z is the vertical displacement in mm. Knowing that the fundamental frequency of each accelerometer is 18000Hz and the damping ratio is 0.80 , answer the followings: a) Calculate the maximum dynamic error in the z measurement. b) Plot the amplitude spectrum of the signal. c) Choose a sampling frequency (fs) (in Hz) such that the shaker vibration can be acquired accurately. d) Determine the period of the signal

If the quality of cars is normally distributed rather than uniformly distributed, the market will not unravel.

In the model, buyers know the utility function of sellers, but do not know anything about the general quality of cars for sale.

If buyers care sufficiently more about cars than do sellers, then there are prices at which transactions can occur. In that scenario, there is no longer any adverse selection (although there still...
