The second runner must run 3.3m/s. If the leading runner is 1.5 seconds ahead and there are 30m left, the second runner would need to run slightly faster than the lead in order to finish at the same time. To calculate this I did 30/1.5 which gave me 0.05. I added this onto the speed of the lead runner to get 3.3m/s :)
Pot conducts heat
Bin Insulates from heat
Plate Insulate from heat and brittle
Explanation:
Any material that is able to conduct heat is known as a conductor. Also, most heat conductors also allows electric current to pass through.
Most metals are categorized as heat conductors. A pot is usually made of conductors which helps to transfer heat to cook food.
Any material that does not conduct heat is called an insulator. Likewise, they do not allow electric current to pass through.
Most non-metals, plastics, rubber, wood, paper are insulators.
A brittle material that breaks into many pieces is a plastic. Their elastic limit is obviously exceeded and they lack internal cohesion and order. A glass used in making plate is also plastic and brittle.
