A sample of mercury-conductor

A piece of glass-insulator

A rubber hose-insulator

A negatively ionized lithium paste-conductor

<u>Step-by-step explanation:</u>

Conductors are substances that allow the flow electricity through them whereas insulators do not permit the flow of electricity through them.

Mercury is  a liquid metal and due to its metallic nature, it is a fair conductor of electricity because metals have free electrons that carry the electric charge through the material.

Rubber and glass are insulators whereas a negatively charged lithium paste is a conductor.

In the diagram triangles ABE and ACD are similar.
jolli1 [7]

Answer:

p = 7.2

q = 6.4

Step-by-step explanation:

if the triangles are similar then the side lengths must be proportional :

AC/BA = CD/BE

9/5 = p/4 cross multiply expressions

5p = 36 divide both sides by 5

p = 7.2

same goes for q

9/5 = (q+8)/8 cross multiply expressions

72 = 5(q+8) divide both sides by 5

14.4 = q+8 subtract 8 from both sides

6.4 = q

Kobotan [32]
Quantitative data refers to any information that can be quantified, counted or measured, and given a numerical value. Qualitative data is descriptive in nature, expressed in terms of language rather than numerical values.
