Answer:
option A
Explanation:
given,
length of antenna = 1 m
traveling at speed = 100 Km/h
Earth's horizontal magnetic field is 5.5 x 10⁻⁵ T
radio antenna doubles in length (l₂ = 2 l)
car begins traveling at a quarter of the original speed (v₂ = v/4)
ratio of new emf
we know, ε = B l v
V₁ = B₁ l₁ v₁...........(1)
V₂ = B₂ l₂ v₂...........(2)
dividing equation (2) from (1)
V₂ = 0.5 V₁
the correct answer is option A
The probability ("odds") is smaller for nonsmokers when compared
to smokers.
If we had as much hard, reliable, repeatable, scientific evidence linking
cardiovascular disease with visits to the Empire State Building as we have
linking it with smoking, the Empire State Building would have been torn down
50 years ago.
Melting point is when a mass goes from solid to liquid, whereas boiling point is when a mass goes from liquid to gas. I hope this helps.
Saying no and not throwing fits and manners.
