Answer:
16 minutes
Step-by-step explanation:
If it takes 63 minutes to paint 9 walls then it means for every wall, it takes 63/9=7 minutes
Since it is 4 people working for 7 mins, the individual rate is 4/7 minutes per person
When we have 7 people, then the number minutes they take will be 7*4/7=4 minutes per wall
4 min per wall for 4 walls then total time will be 4*4=16 minutes
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.
