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.
machines are used to work
Scissors are a simple machine. A simple machine makes work easier to do. (not hard work) What type of simple machine are they? They are a lever. Levers have fulcrums or pivot points. The pivot point of the scissors are the crossing section.
Efficiency % = (work out / work in) * 100 (Work = force * distance)
A toothbrush is not a simple machine, it does not work on the principle of levers, effort, and load. It's not a machine at all in mathematical terms. A "machine" is that which performs "work", i.e. transfers or converts energy. You arm moving the toothbrush is a machine by this definition, however.
A bench vise is used for general work for a typical home owner. A machinist vise is used for precision machine work not to be abused.
explain why a seismograph would not work if the pen vibrated along with the rest of the machine.
why wouldnt women work...we're very powerful people. soo they should work
It wouldnt work
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 otherwise the food chains wouldnt work.
The work done by a machine is the output energy provided by the machine in an intended task, while the work done on a machine is the input energy required to operate the machine. The work done by the machine should ideally be greater than the work done on the machine to ensure efficiency.
The work done on a machine is called input work or mechanical work. It refers to the energy transferred to the machine to operate it and perform tasks.
If the input work is processed by a machine and no output work is produced, the machine is considered to have zero efficiency. This means that the machine is not effectively converting input work into useful output work.
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
Lol. obviously, they wouldnt sell it if it didn't work. there is something called 'batteries' use them.
the work a machine does is the work output what it takes to do the work is the work input
scientists work because, if they didnt then we wouldnt know anything about our earth, plants, our body, humans, animals etc. they work because, they want to earn a living but out of doing it for something they like. if we didnt have science we wouldnt know everything that we know today about us, and how we ivolved.
