Answer:
The bimetallic strip will bend to the iron's way since
When heated copper expands more than iron
Explanation:
bimetallic strips are temperature regulatory devices used to convert a temperature change into mechanical displacement.
It consists of two layers, usually iron and copper which layers are joined together to form the strip owing to the difference in the constants of expansion of the two materials, a flat strip will bend one way (toward the iron part) if heated. The linear thermal expansion coefficient relates the change in temperature to the change in a material's linear dimensions.
Substance is some matter (it can be solid liquid or gas) that has its own properties.. everything in this world are substances...
like for example: the bread that we consume has - wheat ..yeast.. sugar.. salt or some other substances
It is recommended to change or service the automatic transmission fluid for every 30,000 miles. This is the ideal schedule for the average driver and will allow your transmission to run on well fluid continuously, which ultimately means a longer lasting and more efficient transmission. Even though there isn’t any damage in regular fluid changes, they recommend getting it changed every 30,000 to 60,000 miles for better outcomes on your transmission. But there are circumstances where a fluid change should be done sooner, and it will all rest on on your driving routines and other various factors. If you see to do some heavy towing, carrying, common stop-and-go driving, live in a very hot climate, or snow plowing, you should ponder getting your fluid changed sooner, perhaps every 15,000 miles
It is C, gasses with less kinetic energy, i did this and i think i remember it was C
Vector quantites: it is a quantity which has both direction and magnitude.
for example. force which has direction and magnitude both.
scalar quantities: it is a quantity which has magnitude only.
for example. age it has only magnitude.
