The picture shows the inside of an eye.

Which would be found in structure A?

A. retina and optic nerve
B. rods and cones
C. Iris and pupil
D. lens and cornea

Hello, Your answer is D) Lens and Corena

Explanation:

Because the lens goes direct to the light rays and it helps them to focus on light sensitive, and the corena act on a outermost when light strike the corena helps bends or "Refracts" into the income light onto the lens. The only problem it's not "Retina and optic nerve" because the Retina and optic nerve goes to connects the eyes to the brain. And it not B. because the and "Rods and Cone" are responsible for vision at the "Low lights Levels". Maybe it could be C. But the only problem is the "iris and the pupil" are at the ring shape that surrounds at the opening area. So your best answer will be D Lens and Corena. Have a Great day!

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.
