The principle of superposition is the basic principle of geology, which states that on examining the sequence of the strata, the stratum that is younger lies as the top whereas the older one rests at the bottom. This principle applies to the sedimentary rocks. As, the sediments are formed and piled one over the other, the compaction of the sediments occurs due to heat and pressure will result in formation of the sedimentary rocks.
We simplify the cross product first, thereafter the solution of the cross product is now simplified with the dot product as shown in the step by step calculation in the attachment
Motors convert electrical energy into mechanical energy
Explanation:
A motor uses electrical energy to create mechanical energy by creating magnetic fields causing the motor to spin. A generator is the opposite and converts mechanical into electrical by spinning a motor in a magnetic field.
