Pyramid of numbers: relative number of individual organisms at each trophic level in an ecosystem. Pyramids of energy show the relative amount of energy available at each trophic level. On average, about 10 percent of the energy available within one trophic level is transferred to the next trophic level.
HOPE THIS HELPED!!! XD
Answer:
Option C, The magnetic domains inside the material must be aligned
Explanation:
Magnetic domains determine the magnetic behavior of any substance. Most of the magnetic substances have disoriented magnetic domains due to which they do not behave as magnets until unless an external force is applied to change the orientation of their domains and align them properly.
Hence, option C is correct
Answer:
Probably none of the above. it's says directly proportional so there would be a proportionality constant.
S=d/t this is because speed is just the measurement of time and distance
