The limit to the eye’s acuity is actually related to diffraction by the pupil.
(a) what is the angle between two just-resolvable points of light for a 3.00-mm-diameter pupil, assuming an average wavelength of 550 nm?
(b) take your result to be the practical limit for the eye. what is the greatest possible distance a car can be from you if you can resolve its two headlights, given they are 1.30 m apart?
(c) what is the distance between two just-resolvable points held at an arm’s length (0.800 m) from your eye?
(d) how does your answer to (c) compare to details you normally observe in everyday circumstances?

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

b mirrors submit a iisner? e. for which optical devices does d sometimes have a positive value? o a a and b o b. a and c o c. b and d 0 d. b and cb

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
