8) Choose another bird. Compare and contrast this bird to the American crow. If you do not know enough information about a bird, you can imagine that you have discovered a new species of
bird
and make up facts about it.

I would chose to explain the differences between the raven and the American  crow. The raven is usually larger in size with a bigger beak and tail while the American crow is much smaller about the size of a Pidgeon. Another difference is that the raven's tail is "wedge" shaped while the  American crow's is "Fan" shaped. The caws are different as well with the ravens sounding more like a croak and the crows being more frequent and "caw" like.

Explanation:

I went to a bird camp where I  marked  birds and learned to identify them.

Make sure you mark this Maya brainliest this is the best answer all day.

Explanation:

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
