For a lead–tin alloy of composition 80 wt% sn– 20 wt% pb and at 180°c (355°f), do the following: (a) determine the mass fractions of the α and phases. (b) determine the mass fractions of primary and eutectic microconstituents. (c) determine the mass fraction of eutectic

hi there if you are asking for conformation that wavelingth is the correct answer is wrong it is the answer is frequency. : )

i hope this you out, have a wonderful day

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

pls mark as brainliest.

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

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.
