A rigid outer lair covering for the body in some invertebrate animals, especially arthropods, providing both support and protection. and is made of <span>chitin, a substance produced by many non-arthropods as well.</span>
Answer:
The distance that the racecar traveled is indeed 500m. But at the end of the lap, it is right back where it started. So overall, it has been displaced 0m.
Explanation:
Answer:
Explanation:
As the field of current wire passing through the loop is same in direction (normally inward) but not uniform in magnitude.
So, we will use integtation method for finding the flux.
The same flux through a thin reactangular strip of length l and with dx, is given by
dϕB=Bx.dS=B(x)dScos180∘.
Magnetic field due to a long straight wire carrying current I is given by B=μ0I2πx, and area, dS=l×dx.
∴ ϕB=∫dϕB=−∫μ02πIlx.dx=−μ02πIl[logex]x=a+lx=a
=−μ02π.Ill
