explain why a seismograph would not work if the pen vibrated along with the rest of the machine.

I relly don't Know but the thing that I know thet seismograph and richer scale is the same meaning so please check it and write it

THANKS

because if the pen vibrated then the seismograph wouldn't work and it would defeat the purpose. the machine only works if the pen is still. if the pen is still the machine will guide it by the heartbeat lines the pen creates.
