Measuring small quantitiesWatch
We can use:
A 1 metre rule
A balance with precision of 0.1g
A measuring beaker with a precision of 0.1ml
A stop watch with a precision of 0.01s
A voltmeter with precision of 0.01V
An ammeter with a precision of 0.01A
A thermometer with a precision of 0.5K
We can also use any other equipment that doesn't have a scale on it.
We don't necessarily have to measure a physical size; it can be the timing of an event, an electronic charge or any fundamental constants such as Planck's constant, G etc.
We were shown how to measure the size of an atom using an oil droplet and water which I thought, was amazing. Does anyone have any ideas on how we could measure a really small quantity?
Any help will be appreciated and repped
