Answer:
Explanation:
As we know that the displacement of the particle from the mean position is 1/5 times of its amplitude
so we have
so now we have
now we have
so the phase other particle in opposite direction is given as
so we have phase difference given as

Explanation:
Poisonings mostly have no taste or smell. Thallium is one of the poisons that are hard to detect. Most of these poisons are always prescribed to many patients and can be misused. We also have to take into consideration thay poisoning attacks our immune system and internal organs. Side effects of poisoning are flue like. So when the individual is feeling ill. nobody is going to think it’s poison at first until about 30 mins to an hour. that’s why it takes so long to be undetected at first. because of the symptoms, smell, taste..... it can really be easy to poison someone
Answer:
So the induced emf is
Explanation:
Since there is a variation in the current flow on the coil , it means that the magnetic field in the brain would also vary causing an emf to be induced
and from the question the current varies from zero to peak so would the magnetic field vary from zero to peak(i.e from 0 to 0.40T)
This induced emf is mathematically represented as
Where dt =
where
and
So dt
A is the area of the coil mathematically evaluated as
A =
Where
Substituting 2.2cm = for d
Then
Now
Definitely D. The brakes on a bike rub against the wheel. Not sure about the others.
