The use Major changes in mineral deposits in the rock layers.
transformer makes use of mutual induction for its operation in which change in magnetic field in one coil due to variation of current , induces voltage in the other coil. so changing magnetic field in the primary coil is very much needed for the transformer. Alternating current is a current which varies with time , hence it is suitable to produce changing magnetic field in the primary coil. on the other hand , the direct current remains constant all the time. hence can not produce a changing magnetic field. so DC current is not useful for transformers.
We will first record its mass and then its volume by measuring its dimensions
then divide mass by volume and will get density of regular solid
Answer:in X-rays
