Kirchhoff's law of thermal radiation.In heat transfer, Kirchhoff's law of thermal radiation refers to wavelength-specific radiative emission and absorption by a material body in thermodynamic equilibrium, including radiative exchange equilibrium. A body at temperature T radiates electromagnetic energy.
Answer:
Any living or non-living thing trying to take flight will have two forces working against them: gravity and drag. Gravity is the force that the Earth exerts on all things pulling them back towards its centre. ... Birds also have two forces that help them in their attempts to take flight.

Answer:
The correct answer is - the large cross-sectional area and greater length of the cytoplasmic core get less resistance than the smaller cross-sectional area.
Explanation:
The greater length and the large cross-sectional area of the cytoplasmic path or core get less resistance than the resistance of the current path which is the small cross-sectional area of axoplasm. This leads it to greater resistance than the resistance of the current path through the extracellular fluid.
Other than this there is also an unequal distribution of the ions that leads to the increase in potential difference as higher Na+ ions present in cytoplasm and high amount of K+ ion present in axoplasm.
Answer:
Chloroplasts are only found in the parts of the plant that are capable of photosynthesis. The majority of chloroplasts are found in the leaves of the plant because these structures have the greatest surface area for absorption. The outer part of a plant stem may also contain chloroplasts.
