Answer:
c. clockwise
Explanation:
This is because, the magnetic field, B produced due to the downward flowing current in the straight wire is perpendicular to the plane of the rectangular conducting loop and directed outwards from it.
Since it also decreases as it goes from the top of the loop to the bottom of the loop (and also from left to right since B ∝ 1/r), there is a change in magnetic flux which is negative, and thus and induced emf or current is generated to oppose this change in magnetic flux which is generating the current according to Lenz's law. To generate a magnetic field in the opposite direction to that due to the straight wire, a current flowing in the clockwise direction must be generated in the loop.
So the answer is C. clockwise.
Answer:
kinetic energy as it involves dispersal of energy
Answer:
Heat is added to a substance, but its temperature does not rise. Which one of the following statements provides the best explanation for this observation? the substance must be a gas. the substance must be a non-perfect solid. the substance undergoes a change of phase. the substance has unusual thermal properties. the substance must be cooler than its environment.
Answer: approximately 0.0556atoms of 14C
Explanation:
Since 1000atoms of 14C was presently found in the atom that was created 18000years ago. The number of atoms of 14C that will be in that object when it was made will be 1000/18000 which is 0.0556atoms of 14C.
Note that the number of atoms present in it 18000years ago will be a way smaller than present atoms of 14C in it
