Answer:
Graph B represents correct graph for velocity time
Explanation:
Initially the object is dropped under the influence of constant force due to gravity
So here we can say its acceleration is constant due to gravity
hence here the velocity will increase downwards due to gravity and it is given as
now when it enters into the pool an upward force of same magnitude will act on it
so net force on it is
so here we will have no acceleration and it will move with constant speed after that
so here correct graph is
Graph B
12 protons in the nucleus
Biotic is the living factors while abiotic is nonliving such as a rock
Answer:
True
Explanation:
Modern safer and cheaper nuclear reactors can not only meet the range of our long term energy demands, they can also fight global warming.
Modern techniques provide ways to reduce radioactive waste amount. "A closed fuel cycle may be switched on for new kinds of nuclear plants. Alternatively, the waste is chemically dissuaded to transform the reusable element into fuel. This implies that nuclear waste would not be buried.
Answer:
The sympathetic nervous system _____decelerates_______digestion and __accelerates___________blood pressure. See the explanation below, please.
Explanation:
The sympathetic nervous system together with the parasympathetic make up the autonomic nervous system. The sympathetic system acts in situations of stress, prepares the body for "fight or flight", increases heart rate and blood pressure at the cardiovascular level, at the digestive level it slows down the system, produces bronchodilation, pupil dilation (mydriasis).
