Question

what is the answer with explanation??​

Answer 1

The answer is (C) [L^0K-¹]

This can be explained as:-

Increase in length and original length given in the formula is length in any ways. So, it's dimension will be [L] and rise in temperature is Temperature so, it's Dimension is [K].

Now,

alpha can be written as = L/LK, where L cancels L and leaves L^0 and K goes in the numerator with exponent -1 that is [K-¹]
