A second order measuring system has a known natural frequency of 2000 Hz and damping ratio of 0.8. Would it be satisfactory to use it to measure a signal expected to have frequency content at up to 500 Hz? Demonstrate your answer by finding the expected dynamic error and phase shift at 500 Hz.

The  expected dynamic error is  0.019

The phase shift is -23.10°C

Hello.

The first law is "conservation of energy and heat where the total energy in an isolated system may be transformed into another, but never created or destroyed."

So what was realsed in the refrigerator was also realsed from the food.

Have  a nice day
