Explanation:
When marijuana is smoked, THC and other chemicals in the plant pass from the lungs into the bloodstream, which rapidly carries them throughout the body to the brain. The person begins to experience effects almost immediately (see "How does marijuana produce its effects?"). Many people experience a pleasant euphoria and sense of relaxation. Other common effects, which may vary dramatically among different people, include heightened sensory perception (e.g., brighter colors), laughter, altered perception of time, and increased appetite.
If marijuana is consumed in foods or beverages, these effects are somewhat delayed—usually appearing after 30 minutes to 1 hour—because the drug must first pass through the digestive system. Eating or drinking marijuana delivers significantly less THC into the bloodstream than smoking an equivalent amount of the plant. Because of the delayed effects, people may inadvertently consume more THC than they intend to.
Pleasant experiences with marijuana are by no means universal. Instead of relaxation and euphoria, some people experience anxiety, fear, distrust, or panic. These effects are more common when a person takes too much, the marijuana has an unexpectedly high potency, or the person is inexperienced. People who have taken large doses of marijuana may experience an acute psychosis, which includes hallucinations, delusions, and a loss of the sense of personal identity. These unpleasant but temporary reactions are distinct from longer-lasting psychotic disorders, such as schizophrenia, that may be associated with the use of marijuana in vulnerable individuals. (See "Is there a link between marijuana use and psychiatric disorders?")
Although detectable amounts of THC may remain in the body for days or even weeks after use, the noticeable effects of smoked marijuana generally last from 1 to 3 hours, and those of marijuana consumed in food or drink may last for many hours.
Answer:
Explanation:
This question seek to test the difference between a scalar and a vector quantity. A scalar quantity is a quantity that has just magnitude but no direction while a vector quantity is a quantity that has both magnitude and direction. Example of a scalar quantity is speed while example of a vector quantity is velocity.
Hence, it can be that <u>speed has magnitude but no direction while velocity has both magnitude and direction</u>.
They both have the same formula which can be written as
speed = distance ÷ time
OR as
velocity = distance ÷ time
Answer:
2.82 D
Explanation:
Near point of the person eye is 85 cm that is
He wants to see the object at 25 cm so
For the lens we know that
\frac{1}{f}=0.04-0.01170=0.02823
We know that power of the lens
So
The answer is B. Have a good day! :)
