Mechanical to sound to radiant
chemical energy--->mechanical energy--->sound energy
240 ohms
The alarm would be much quieter, as sound can't travel through vacuum. But if it's a mechanical alarm clock then vibrations would be transferred from the clock to the jar and then to whatever the clock is standing on , and you'd probably be able to hear some of that.
you just have to put an alarm for a couple days then you will get used to it and dont have to have an alarm :J
According to Selye, a person exerts an all-out effort to combat stress at the interface between the alarm reaction and the stage of resistance.
An alarm clock does not have a chemical name. It is a mechanical or electro-mechanical device.
Mechanical to sound to radiant
Mechanical to sound to radiant
Heat changes the resistance of a circuit. The change is detected by the system, and activates the alarm.
please tell me the answer of when were mechanicalclocks first used
chemical energy--->mechanical energy--->sound energy
An early prototype of the alarm clock was invented by the Greeks around 250 BC. The Greeks built a water clock where the raising waters would both keep time and eventually hit a mechanical bird that triggered an alarming whistle. The first mechanical alarm clock was invented by Levi Hutchins of Concord, New Hampshire, in 1787. However, the ringing bell alarm on his clock could ring only at 4 am. On October 24, 1876 a mechanical wind-up alarm clock that could be set for any time was patented (#183,725) by Seth E Thomas.
Alarm Resistance Cycle.
An initial reaction to something alarming would be the alarm stage. This is when the adrenaline courses through the body. The resistance stage comes after the alarm stage, and this is when the body repairs any damage to the system that had been caused by the alarm stage.
