Velocity is measured by (final velocity - initial velocity)/time taken, or simply put, change in velocity/time taken. Our original velocity was 8, and our final was 22.
With our information, subtract 22 by 8 and then divide by 7 (final - inital)/(time taken).
22-8 = 14
14/7 = 2.
Your average acceleration was 2.0 m/s^2.
The answer is D.)
I hope this helps!
Answer: First it becomes a theory and a well established theory becomes a law. But the theory must be able to be proven.

Correct option is
A
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Prokaryotic cells have a cell wall surrounding the cell membrane. The fluid matrix filling the cell is the cytoplasm. There is no well-defined nucleus. The genetic material is basically naked in the cytoplasm, not enveloped by a nuclear membrane. The nuclear membrane is found in eukaryotes. The prokaryotic cells lack mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, microtubules, microfilaments, and centrioles.
Cytoplasmic streaming, also called cyclosis, is the directed flow of cytosol (the liquid component of the cytoplasm) and organelles that aids in the delivery of organelles, nutrients, metabolites, genetic information, and other materials to all parts of the cell. In prokaryotes, cytoplasm does not show cyclosis or streaming movements.
So, the answer is A.
A runaway greenhouse effect is a process in which a net positive feedback between surface temperature and atmospheric opacity increases the strength of the greenhouse effect on a planet until its oceans boil away. An example of this is believed to have happened in the early history of Venus.
