During a classroom demonstration, the instructor clumsily fails in an attempt to push a 2.001 cm diameter brass sphere through a 1.999 cm opening in a steel ring. the instructor then heats the steel ring until the sphere “just” slips through the opening. if the initial temperature of the ring is 20.0 oc, calculate the minimum temperature of the ring at which the sphere slips through the hole. note that the coefficient of linear expansion of steel is 12x10-6 oc-1

the answer would be a

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
