How are the movements of the moon in the sky and earth's rotation about its own axis related? a) the moon appears to move from east to west due to earth's east-to-west rotation. b) the moon appears to move from east to west due to earth's west-to-east rotation. c) the moon actually moves from east to west while earth rotates from west to east. d) the moon and earth both move from east to west, but earth rotates at a lower speed.

The moon orbits quite fast: it moves about 0.5 degrees per hour in the sky. In 24 hours it moves 13 degrees. The moon's observed motion eastward results from its physical motion of the moon along its orbit around the Earth. so I think its A .

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
