1. Where is the fulcrum of this lever? Circle and label its location on the diagram above.

This question is incomplete

Explanation:

This question is incomplete because of the absence of the required diagram. The required diagram has however been attached to this answer with the fulcrum circled.

A fulcrum is a pivot point in a lever; it plays a centre role (but might not be at the centre) which usually determines the activity of a lever. An example of a fulcrum is the circled part in the attachment.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
